Construct a system configuration that considers the startup time of other devices. 0 Maximum boost current 0 Rated current Note: Refer to Overload Protection on page 17 Overvoltage Protection Consider the possibility of an overvoltage and design the system so that the load will not be subjected to an excessive voltage even if the feedback circuit in the Power Supply fails. When an excessive voltage that is approximately 130% of the rated voltage or higher is output, the output voltage is shut OFF, preventing damage to the load due to overvoltage. To reset the protection, turn OFF the input power for three minutes or longer and then turn it back ON.

Do not allow contact with a conductor after power-on, withstand voltage testing, or insulation resistance testing. Residual voltage may cause failure, deterioration, or electrical shock. Precautions for Safe Use Wiring • Connect the ground completely. A protective earthing terminal stipulated in safety standards is used. Electric shock or malfunction may occur if the ground is not connected completely. • The light ignition may possibly be caused. Ensure that input and output terminals are wired correctly. • Be sure to remove the sheet covering the product for machining before power-ON so that it does not interfere with heat dissipation. • Always select wire sizes suitable for at least 1.6 times the rated current to prevent heating and ignition of wire materials due to load abnormalities. Refer to the wiring manufacturer’s recommended allowable current and voltage drop specifications for information when selecting wiring materials. • The current rating for the output terminal is 5A per terminal. Make sure to use multiple terminals together if a current exceeding the terminal rating is used. • Use wiring materials with a UL recognized temperature of 60°C min. or 60°C/75°C min. • Use wiring materials with copper conductors. • Refer to Input and Output Connectors on page 6 for the model numbers of the Input and Output Connectors. Do not insert and remove any connector more than 20 times. Installation Environment • Avoid places subject to shock or vibration. A device such as a contact breaker may be a vibration source. Set the Power Supply as far as possible from possible sources of shock or vibration. • If the Power Supply is used in an area with excessive electronic noise, be sure to separate the Power Supply as far as possible from the noise and surge sources. Ambient Operating and Storage Environments • Store the product with ambient temperature −25 to 75°C, and relative humidity 25 to 90%. • The internal parts may occasionally be deteriorated or broken. Do not use the product outside the derating range. • Use the product where the relative humidity is 25 to 85%. • Avoid places where the product is subjected to direct sunlight. • Avoid places where the product is subjected to penetration of liquid, foreign substance, or corrosive gas Minor electric shock, fire, or Product failure may occasionally occur. Do not allow any pieces of metal or conductors or any clippings or cuttings resulting from installation work to enter the Product. 15 S8EA Precautions for Correct Use Mounting Series Operation Two Power Supplies can be connected in series. The ± voltage output can be accomplished with two Power Supplies. Mounting Interval 4 mm min.

Locations of Mounting Holes on Open-frame Models 8 mm 8 mm 8 mm 8 mm CN1 8 mm 8 mm 8 mm 8 mm • Install the Power Supply so that heat is effectively dissipated to improve and maintain the reliability of the Power Supply over a long period of time. • The S8EA uses natural convection. Mount so that convection of the air around the power unit can take place. • The crosshatching indicates the allowable range for the mounted metal part. • When mounting, use the mounting holes in the board and spacers to mount at least 8 mm off the board. This a clearance of 4 mm space is necessary to satisfy the insulation and withstand voltage standards. • Metal plate is strongly recommended as the mounting panel. Note: 1. Do not subject the board to stress such as twisting, bending, or shock. This may cause failure or deterioration. 2. During assembly, do not subject the lead feet or surface mounted parts to stress. This may cause failure or deterioration. • Depending on how the Power Supply is mounted, the heat dissipating capacity may be reduced and cause deterioration to or damage the internal components. • The internal parts may occasionally deteriorate and be broken due to adverse heat radiation. Do not loosen the screws on the Power Supply. Output Voltage Adjuster (V. ADJ) Default Setting: Set at the rated voltage. Adjustment Range: The output voltage can be adjusted to ±10% of the rated voltage with the voltage output adjuster (V. ADJ) on the front panel. Turning clockwise increases the output voltage, and turning counterclockwise decreases the output voltage. • The output voltage adjuster (V. ADJ) may possibly be damaged if it is turned with unnecessary force. Do not turn the adjuster with excessive force. • After completing output voltage adjustment, be sure that the output capacity or output current does not exceed the rated output capacity or rated output current. • Adjusting the output voltage adjuster (V. ADJ) may cause the output voltage to exceed the voltage range. When adjusting the output voltage, check the output voltage of the Power Supply and be sure that the load is not destroyed. 16 Note: 1. If the load is short-circuited, a reverse voltage will be generated inside the Power Supply. If this occurs, the Power Supply may possibly deteriorate or be damaged. Always connect diodes as shown in the figure. Select diodes with the following ratings. Type Schottky Barrier diode Dielectric strength (VRRM) Twice the rated output voltage or above Forward current (IF) Twice the rated output current or above 2. Although Products having different specifications can be connected in series, the current flowing through the load must not exceed the smaller rated output current. Parallel Operation The Product is not designed for parallel operation. Parallel Operation Incorrect AC(L) +V AC(N) −V AC(L) +V AC(N) −V However, the following backup operation is possible. (External diodes are required.) A D1 +V Load 4 mm min. CN1 −V B D2 +V −V Use the same model for Power Supplies A and B. • Type: Schottky barrier diode • Dielectric strength (VRRM): Rated output voltage of the Power Supply or higher • Forward current (IF): Twice the rated output current of the Power Supply or higher • Set the output voltages of Power Supplies A and B higher to compensate for the decrease of the forward voltages (VF) of diodes D1 and D2. Also, there will be a power loss equivalent to the output current (IOUT) of the Power Supply multiplied by the forward voltage (VF) of the diode. Therefore, cooling will be required to keep the temperature of the diodes lower than the catalog value. • There will be a power loss caused by load power and diodes. Be sure not to exceed the rated power (rated output voltage times rated output current) of each Power Supply. S8EA Overload Protection Ripple Noise Voltage • Internal parts may possibly deteriorate or be damaged if a shortcircuited, overload or boost load state continues during operation. • Internal parts may possibly deteriorate or be damaged if the Power Supply is used for applications with frequent inrush current or overloading at the load end. Do not use the Power Supply for such applications. Charging Batteries When connecting a battery at the load, connect an overcurrentlimiting circuit and overvoltage protection circuit. The specified standard for the ripple voltage noise was measured with a measurement circuit that is based on JEITA standard RC-9131B. +V C1 C2 S8EA Load −V 150 mm C1: 100 μF C2: 0.1 μF Coaxial cable Oscilloscope frequency band: 100 MHz In Case There Is No Output Voltage A possible cause for no output voltage may be that the overcurrent or overvoltage protection has operated. The internal protection may operate if a large amount of surge voltage, such as a lightening surge, is applied to the input. In case there is no output voltage, please check the following points before contacting us: • Checking the Overcurrent Protected Status Check whether the load is in overcurrent status or is shortcircuited. Remove wires to load when checking. • Checking overvoltage or internal protection: Turn the power supply OFF once, and leave it OFF for at least 3 minutes for S8EA series. Then turn it ON again to see if this clears the condition. Power Boost Function • Do not allow the boost current to continue for more than 10 seconds. Also, do not let the duty cycle exceed the following conditions. This may damage the Power Supply. • Lessen the load of the boosted load current by adjusting the ambient temperature and the mounting direction. • Ensure that the average current of one cycle of the boost current does not exceed the specified value. This may damage the Power Supply. lp: Boost current Output current [A] lave: Average current t1 t2 Models S8EA-BN05024@ (50 W) S8EA-BN07524@ (75 W) S8EA-BN10024@ (100 W) S8EA-BN15024@ (150 W) Boost current conditions • 90 to 132 VAC • t1 ≤ 10 s • lp ≤ Rated boost current • lave ≤ Rated current t1 • Duty = × 100[%] ≤ 35% t1+t2 Note: Make sure that the boost current meets the above conditions.
