MST-MHT SERIES 071320
1-7/(1-8 Blank)
1.4.6 SERIES CONFIGURATIONS
The output of the MST-MHT Power Module “floats;” so that MST-MHT Power Modules can be
connected in series to obtain higher output voltages, up to a maximum of ± 500 Volts d-c (±400
Volts d-c when Adapter KIT 219-0618 is installed on the OUTPUT connector at the rack
adapter) referenced to the chassis (see PAR. 3.6).
1.4.7 PARALLEL CONFIGURATION
A parallel configuration may be employed for higher output current and for N + 1 redundant,
“hot-swap” applications. When connected in a parallel configuration, MST-MHT Power Modules
employ forced current sharing to ensure equal distribution of the load among all power modules,
improving performance, reducing component stress, and increasing reliability (see PAR. 3.5).
1.5 OPTIONS
The HT option (HT appended to the Model Number, e.g., MST 6-20MHT) incorporates addi-
tional filtering to provide significant output noise reduction in the range of 1KHz to 10MHz, com-
patible with Keysight/Agilent/HP 66000© mainframe. Contact Kepco Sales Engineering for
additional information regarding performance and availability of other options such as output
current monitoring where a 0 to 2V signal corresponds to 0 to I
NOM
.
1.6 ACCESSORIES
The MST-MHT Power Module is designed for installation in Kepco Rack Adapter Model RA 55H
which accommodates nine 1/9 rack size power modules. With a 1/9 rack Controller module
installed, the RA 55H will accommodate eight 1/9 rack power modules. Connecting cables and
IEEE 1118 bus daisy chain terminations are supplied with the RA 55H Rack Adapter. Additional
accessories are listed in Table 1-3.

OUTPUT LOAD CONNECTOR
ADAPTER (supplied with RA
55H Rack Adapter) KIT 219-0618 Allows output load connections of up to 20 Amperes to MST-MHT
power module not installed in RA 55H Rack Adapter (for advanced
troubleshooting). Adapter is terminated at one end with mating con-
nector for MST-MHT module output connector. The opposite end is
terminated with 6 terminals having crimp-ready ring lugs used for out-
put power, sensing, ground and load sharing connections. This
adapter is typically used in conjunction with 118-0850 Input Power/
Communication Cable.
INPUT POWER/COMMUNICA-
TION CABLE (Used for stand-
alone module Communication/
calibration) 118-0850 Allows power and communication connections to MST-MHT power
module not installed in RA 55H Rack Adapter (for advanced trouble-
shooting). Cable length is approximately 7 feet, terminated at one end
with mating connector for MST-MHT module a-c input/control bus con-
nector. The opposite end of the cable is split into two terminations, one
a NEMA 5-20P a-c mains plug and the other a 9-pin D-sub connector
that mates with the control bus connector of RA 55H (as well as CA
400H and MST 488-27HT). This cable is typically used in conjunction
with Kit 219-0618 Output Load Connector Adapter.
MATING CONNECTOR
(DC OUTPUT) (Used for Calibra-
tion)
142-0372
Mates with DC OUTPUT connector, Kepco P/N 143-0457 (Positronic
POW-R-LOK Series 6 pin connector). This item is typically used in
conjunction with 118-0850 Input Power/Communication Cable.
LOAD CONNECTOR PINS
(Used for Calibration)
107-0327
Replacement pins for DC OUTPUT connector. This item is typically
used in conjunction with 118-0850 Input Power/Communication Cable.
