I — INTRODUCTION
SCOPE OF MANUAL. This instruction manual covers
the installation and operation of the Kepco RMW 300W
Series of RoHS-compliant Open Frame PFC (Power Factor
Corrected) Switching Power Supplies.
DESCRIPTION. Kepco RMW Series are 300W RoHS-
compliant switching power supplies with seven models pro-
viding 5V, 12V, 15V, 24V, 28V, 48V and a triple output
model (RMW 51212K-300) which provides a primary output
of +5V and secondary outputs of ±12V). All models include
1) a separate +12V output that can be used to power an
external cooling fan (not supplied), 2) a separate output
that can be used to drive a “Power OK” LED (not supplied).
Remote sensing capability (compensation 0.5V per lead)
and Power Factor Correction (PFC) is included in all mod-
els.
Units may be operated with nominal 115V a-c or 230V a-c
(input voltage range 85 to 264 Va-c), 50-60 Hz (input fre-
quency range 47-63Hz). Units operate up to 400Hz
although leakage current, power factor and efficiency spec-
ifications may not be met. They will also operate on 120V to
370V d-c input. Units are convection cooled U-chassis con-
struction.
Specifications and operating limits for individual RMW
300W models are listed in Table 1. Section II contains
specifications and operating limits common to all RMW
300W Series Models. Section III describes RMW 300W
features. Section IV describes installation and Section V
describes operation.

(1)
The +5V output is preset to between 4.95V and 5.05V for 60% of rated load and nominal input line while the other outputs are verified
to be within the specified accuracy range.
(2)
An overvoltage shuts down the output. Recover by recycling a-c input.
(3)
Overcurrent protection point: 120% - 150% of rated load current, auto-recovery (except for 5V models which latch off).
(4)
Requires 18 CFM (22 CFM for 24V, 28V and 48V models) forced air cooling.
(5)
85% efficiency for all three outputs combined.
