EPW30-48A-E Power Module
User Manual
1 Features
EPW50-48A-E power module (module for short) uses soft-switching
and input / output soft start-up technology. Its output can be
regulated through monitoring. Multiple modules can be paralleled to
share the load.

4 Protection
Refer to Table 1 for the protection functions.
Table 1 Protection functions
Input overvoltage
protection
The module will send alarm and shutdown
when the input is above 305Vac; and recover
when the input drops down 300Vac
Input
undervoltage
protection
The module will send alarm and shutdown
when the input is below 85Vac; and recover
when the input increases above 90Vac
Output
overvoltage
protection
The protection point is 58.5 ~ 60.5Vdc. The
module will shutdown to lock upon the
overvoltage status. Restart the module after
the protection is removed
Current limit
protection
The module has current limit
protection:2900W (176 ~ 220Vac input);
1200W (90 ~ 175Vac input)
Short circuit
protection
The module has short circuit protection. The
module output 61A upon shortcircuit. The
module will recover when the fault is removed
Overtemperature
protection
The module will send alarm and shutdown
when the testing temperature is above 116°C;
and recovery when the temperature is under
110°C
The module will send alarm through alarm indicators upon input
over- and under- voltage, output over-voltage, and module fault.
5 Input And Output Connectors
EPW50-27A-E power module connects to user system through its
interfaces: AC input socket (FCI, 51939-021); DC output socket (FCI,
51939-022), which also serves as the signal interface. Their pin
locations are shown in Figure 1 and pin definitions are listed in
Table 2.
