An input line fuse must always be used. This power module can be used in a wide variety of applications, ranging from simple standalone operation to being part of complex power architecture. To preserve maximum flexibility, internal fusing is not included; however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a fastacting fuse with a maximum rating of 6A (see Safety Considerations section). Based on the information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be used. Refer to the fuse manufacturer’s data sheet for further information.

Feature Descriptions Remote On/Off One pole of the input and one pole of the output are to be grounded, or both circuits are to be kept floating, to maintain the output voltage to ground voltage within ELV or SELV limits. For all input sources, other than DC MAINS, where the input voltage is between 60 and 75V dc (Classified as TNV-2 in Europe), the following must be meet, if the converter’s output is to be evaluated for SELV: Two remote On/Off logic options are available. Positive logic remote On/Off turns the module ON during a logichigh voltage on the remote On/Off pin, and turns the module OFF during a logic-low. Negative logic remote On/Off turns the module OFF during a logic-high and turns the module ON during logic-low. Negative logic is specified by suffix “1” at the end of the device code. To turn the power module on and off, the user must supply a switch to control the voltage between the ON/OFF pin and the VIN(–) terminal (Von/Off).

Circuit configuration for using Remote On/Off Implementation. Overcurrent Protection To provide protection in a fault (output overload) condition, the module is equipped with internal current-limiting circuitry, and can endure current limiting continuously. At the instance of current-limit inception, the output current begins to tail-out. When an overcurrent condition exists beyond a few seconds, the module enters a “hiccup” mode of operation, whereby it shuts down and automatically attempts to restart.. While the fault condition exists, the module will remain in this hiccup mode, and can remain in this mode until the fault is cleared.

Input Undervoltage Lockout be increased, which, at the same output current, would increase the power output of the module. Care should be taken to ensure that the maximum output power of the module remains at or below the maximum rated power (Maximum rated power = Vo,set x Io,max). At input voltages below the input undervoltage lockout limit, the module operation is disabled. The module will begin to operate at an input voltage between the undervoltage lockout limit and the minimum operating input voltage.

The module will automatically restart after it cools down. Output Voltage Programming Trimming allows the user to increase or decrease the output voltage set point of a module. This is accomplished by connecting an external resistor The output overvoltage protection clamp consists of between the TRIM pin and either the SENSE(+) or control circuitry, independent of the primary regulation SENSE(-) pins. A resistor placed between the Trim pin loop, which monitors the voltage on the output and Sense (+) increases the output voltage and a terminals. This control loop has a higher voltage set resistor placed between the Trim pin and Sense (-) point than the primary loop (See the overvoltage clamp decreases the output voltage. Figure 12 shows the values in the Feature Specifications). In a fault circuit configuration using an external resistor. The trim condition, the overvoltage clamp ensures that the output resistor should be positioned close to the module. If the voltage does not exceed Vo, clamp(max). This provides a trim pin is not used then the pin shall be left open. redundant voltage-control that reduces the risk of output overvoltage. Over Voltage Protection Remote sense Remote sense minimizes the effects of distribution losses by regulating the voltage at the remote-sense connections (See Figure 11). The voltage between the remote-sense pins and the output terminals must not exceed the output voltage sense range given in the Feature Specifications table: [VO(+) – VO(–)] – [SENSE(+) – SENSE(–)] ≤ 10% of VO,rated The voltage between the VO(+) and VO(–) terminals must not exceed the minimum output overvoltage shutdown value indicated in the Feature Specifications table. This limit includes any increase in voltage due to remotesense compensation and output voltage setpoint adjustment (trim) (see Figure 11).
