S82D S82D Engineering Data Derating Curve Overvoltage Protection Output voltage (V) Load (%) The protective function prevents damage to the load as well as the Power Supply itself due to overvoltage. The output is shut off if the output voltage rises above about 120% of the rated voltage. The input power must be turned off for at least 30 s, and then turned on again to reset the Power Supply. Overvoltage Approx. 20% 10% Rated output voltage –10% Variable Ambient temperature (°C) Note: The derating curve differs depending on the mounting direction of the Power Supply. The curve above was obtained with the Power Supply mounted in the standard position. Inrush Current, Rise Time, Hold Time Overload Protection The protective function prevents damage to the load as well as the Power Supply itself due to overload. If the load current rises above the overload set value (105% of the rated load current), the protective function will engage and the voltage will be reduced. Reset is automatic, so the Power Supply will return to normal operation when the overload condition is corrected. If an overload condition continues for more than 5 s, the output will be shut off. In this situation, reset is not automatic. The input power must be turned off for at least 30 s, and then turned on again to reset the Power Supply.

Output current (%) Output shut off after 5 s 3 S82D S82D Operation Remote Sensing Function Remote Control Function This function corrects a voltage drop in the load wiring. When using the remote sensing function, remove the short bars from the remote sensing terminals as shown in the following diagram. This function allows the output voltage to be turned on and off with an external signal (as long as the input voltage is being applied). When using the remote control function, remove the short bar (attached at ex-factory condition) from the remote control terminals and connect a switch or transistor as shown in the diagram below. Remote sensing connection (2-wire shielded cable) Tr* Load Remove the short bar Remove the short bar Load wiring *Use a transistor with VCE > 20 V and Ic > 5 mA. Note: 1. When the voltage drop in the load wiring is large, the overvoltage protection function might engage just from the increase in voltage to correct the voltage drop, so be sure to use high capacity wiring. 2. If the +S and +V terminals are left unconnected, the high voltage protection function will engage and the output voltage will be cut off. If the -S and -V terminals are left unconnected, the output voltage will increase about 5%. Level Output voltage L (0.8 V max.) ON H (2 V min.)

S82D S82D Precautions Mounting Terminal Expansion Bracket Providing adequate cooling when installing the Power Supply will extend its long-term reliability. When installing two or more Power Supplies side-by-side, allow at least 10 mm spacing between them, as shown in the diagram below. A terminal expansion bracket is available for use with the 600 W Power Supply when several loads need to be connected. S82Y-D60T 10 mm min. Brackets: 2 M4 x 8 terminal screws: 12 M5 x 12 terminal screws: 4 Replacing the Fan The Power Supply is cooled by air forced through it by the internal fan. Don’t obstruct the ventilation holes in the front and back surfaces of the unit. 300 W: 40 mm min. 600 W: 50 mm min. It is necessary to replace the internal fan when the fan alarm output goes ON. Replacement fans can be ordered through your dealer. To replace the fan, remove the back cover as shown in the diagram below. PCB Body Connector for fan Fan Back cover Fan Take care to minimize dirt, dust, and other air-borne debris which could interfere with the passage of cooling air. Switching the Input Voltage between 100 to 120 and 200 to 240 V Generating Output Voltages (±) S82D Power Supplies may be connected to provide floating output voltages (±) as shown below. Select 100 to 120 or 200 to 240 V input voltage by shorting or opening the input voltage switching terminals, as shown in the diagram below. (Factory set to 200 to 240 V operation.) 100 to 120 V Input Series Connection The output of two Power Supplies can be combined in series to double the output voltage as shown below. 100 to 120 VAC 200 to 240 V Input 200 to 240 VAC Shorted with the short bar Open 7 S82D S82D Parallel Connection (Master/Slave Operation) The model S82D Power Supply has a built-in current balance function, allowing two units to be connected in parallel (master/slave operation) increasing the output current. Master/Slave Operation When connecting two Power Supplies for master/slave operation, use shielded wire to connect the current balance (CB) and -S terminals as shown below. Shielded wire CB –S +V CB –S –V Wiring Use high capacity wiring between the Power Supplies and the load in order to minimize voltage drops due to wire resistance. A parallel connection kit (sold separately) is available. The kit includes a bar to connect the outputs, and shielded wire to connect the current balance and -S terminals.

S82D-3012 (–) (+) Load In master/slave operation, the Power Supply with the lower voltage adjustment set value (controlled by V. ADJ) is the master unit, and the Power Supply with the higher voltage adjustment set value is the slave unit. NOTICE A maximum of two units can be connected in parallel. Block Diagram To ensure that the voltage drop is the same between each Power Supply and load, the length and cross sectional area of the wires used should be uniform, and the system should be wired as in figure below. Shielded wire Shielded wire CB –S +V CB –S –V +V CB –S –V +V CB –S –V (–) (+) Load +V –V (–) (+) Load Do not wire the Power Supplies as shown below. It will cause output voltage imbalance, so that one of the units will supply exceeding current, causing the overload protection to engage, resulting in an unstable current and reducing product life expectancy. Shielded wire CB –S +V –V CB –S +V –V Adjusting the Output Voltage Follow the procedure below when adjusting the output voltage of a master/slave system. 1. Connect the two Power Supplies in parallel and decide which unit will be the master. 2. Turn the voltage adjuster (V. ADJ) of the slave unit all the way clockwise. 3. Adjust the voltage adjuster (V. ADJ) of the master unit to the desired voltage. 4. Slowly turn the voltage adjuster (V. ADJ) of the slave unit counterclockwise and set value just before output voltage drop. NOTICE 1. It is recommended to set equal output voltages to both Power Supplies for safety reasons. If the master Power Supply stops operation by input failure or breakage, the set output value of the slave Power Supply will be output. 2. Even if one Power Supply fails to operate, both output LED indicators may be lit if the other Power Supply is in operation. (+) (–) Load ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
