SECTION 1 - INTRODUCTION
1.1 SCOPE OF MANUAL
This manual contains instructions for the installation, operation, and maintenance of the MST-
MHT series of 200 Watt, voltage and current stabilized d-c programmable power supplies
(power modules) manufactured by Kepco, Inc., Flushing, New York, U.S.A. when controlled by a
Kepco Model MST 488-27HT Controller.
Details regarding the MST 488-27HT Controller can be found in the MST 488-27HT Controller
Operator Manual which is available for download from the Kepco website at:

Details regarding the RA 55 Connector Adapter can be found in the Kit 219-0618 RA 55 Con-
nector Adapter Kit Instruction Sheet which is available for download from the Kepco website at:

1.2 DESCRIPTION
The Kepco MST-MHT 200 Watt Series (Figure 1-1) consists of eight, single-output models as
shown in Table 1-1. MST-MHT Series Power Modules are designed to provide a functional drop-
in replacement for Keysight/Agilent/HP Series 66000A© power modules. These models also
include the following additional features: autoranging a-c input, PFC to meet IEC/EN require-
ments, current share, hot swap, built-in polarity reversal, constant current mode and greater
power (180W to 200W).
MST-MHT power modules employ a switch mode preregulator for high efficiency and power
density, with linear output stabilization for accuracy and resolution. Their modular, plug-in design
with 7" x 1-3/4” cross-section allows nine independently controlled modules to be mounted
abreast in a standard (19" x 7" x 20.9") Kepco Model RA 55H rack adapter or 5 modules in a
standard (9.6” x 7” x 20.9”) Kepco Model CA 400H case.
Each Power Module is controlled digitally via the IEEE 1118 2-wire serial bus (“Bitbus”) with 12
bits of resolution over the entire voltage and current ranges. Voltage and current are displayed
on LED panel meters, and read back over the control bus with an accuracy of 0.06%. Operating
status is displayed on front panel LED indicators and read back over the bus.
An MST-MHT Power Module can be removed and installed without powering down the system if
the module POWER switch is set to OFF. Employing current-sharing for parallel operation, they
may be “hot-swapped” for redundant (N+1) applications. MST-MHT Power Supplies can be
operated with universal a-c input power sources (90-264Vac, 47-63Hz) and incorporate power
factor correction (0.98) to meet EN 61000-3-2. MST-MHT Power Modules can also be config-
ured in series for higher than rated output voltages (500V d-c maximum)
