Conditions of Conformance
When this product i s used in applications governed by the re quirements of the EEC, the following restric -
tions and conditions ap ply:
1. For European applic ations, requiring com pliance to the Low Voltage Directive, 7 3/23/EEC, this power
supply is consid ered a component prod uct, designed f or "built in“ appli cations. Becaus e it is incom-
plete in construction, the end product enc losure must pr ovide for compliance to any remaining e lectri-
cal safety requireme nts and act as a fire enc losure. (EN61010- 1:2001, Cl. 6, Cl. 7, Cl.8, a nd Cl. 9)
2. This power supply i s designed for stationa ry installation, wi th mains power applie d via a detachable
power supply cord or via direct wirin g to the source powe r term inal bloc k.
3. This power supply i s considered a Class 1 ( earthed) product. It is intended for use as part of equip-
ment meant for test, measurement and laborat ory use, and is des igned to operate from single phase,
three wire power syst ems. This equip ment must be instal led within a suita bly wired equipment r ack,
utilizing a three wire ( grounded) mains conne ction. See wiring s ection of this manu al for complete
electrical wiring instruct ion s. (EN61 010 -1:200 1, C l.6.10.1 )
4. This power supply ha s secondary ou tput circuits that are c onsidered hazard ous, and which excee d
240 VA at a potential of 2V or more.
5. The output wiring terminal s of this power supply has n ot been evaluated for field wiring and, therefore,
must be properly conf igured by the end pro duct manufacturer pri or to use.
6. This power supply em ploys a supplem entary circuit prote ctor in the form of a c ircuit breaker moun ted
on the front panel. Th is circuit breaker pr otects the power sup ply itself from dama ge in the event of a
fault condition. For c omplete circuit prot ection of the end produ ct, as well as the bui lding wiring, it is
required that a primary circuit protection dev ice be fitted to the branc h circuit wiring. (EN61 010-
1:2001, Cl. 9.5)
7. Hazardous voltages are present within this power supp ly during normal operat ion. All operator ad just-
ments to the product a re made via externa lly accessible switch es, controls and sign al lines as speci-
fied within the produc t operating instructio ns. There are no user or operator service able parts within
the product enclosu re. Refer all serv icing to qualified an d trained Kepco ser vice technicians .

SECTION 1 - INTRODUCTION 1.1 SCOPE OF MANUAL This manual c ontains instructions for the i nstallation, operation, and m aintenance of the Full
Rack si ze MAT series of volt age and curren t stabi lized DC Po wer Modul es man ufactured by
Kepco, Inc. Flushing, New York, U.S.A.
1.2 GENERAL DESCRIPTION The Kepco MA T Power Mod ule with overvoltage, overcur rent, overtemperature , p olarity rever-
sal, a nd power loss protection is a dig itally c ontrolled precision s tabilized Power Module that
delivers eithe r stabilized voltage or current. A single front panel meter with a selec tor switch
constantly moni tors the output voltage or the out put current. The prevailing operating mode is
indicated by LED mode indicato rs on the fr ont p anel. Operating mode cross over is dependent
on commands from a Host Computer and the value of the load. The Power Module has a linear
and fully d issipative NPN p ass transi stor driven by high gain integrated circuit amplifiers. The
output of the Power Modu le is fully programm able
The Power Modu le features f ull range out put control b y means of a c ompatible Kepco Power
Module Controller. Control of t he MA T Power Module is via th e IEEE 1 1 18 2-wire serial bus
operating at 37 5KHz; as ma ny as 27 s eparate modules of either the MAT , M ST , MBT or BOP
Series design can be addressed vi a the bus (see Figure 1-1). Decoders for RS232, IEE E-488
and VXI are available in modular form and stand -alone types. As shown in Figure 1-1 , the fo l-
lowing controllers are avai lable to control of MAT Power Modules directly from a computer.
a. Controller Mo del TMA P C-27 plugs into a hal f-card slot of a DO S-based PC and allow s key-
board control of the MAT via the IEEE 1 1 18 bus.
b. Controller Model TMA 4882-27 is free- standing and allows host computers design ed for
RS232 or IEEE 488 bus communic ation to control the MAT via the IEEE 1 1 18 bus.
c. Con troller Model TMA-VXI-27 plugs into a slot in a VXI chassi s and allo ws VXI- based com-
puters to control the MAT via the IEEE 1 1 18 bus.
d. Controller Model MST 488-2 7 plugs into a slot in a Model RA 55 Rack Adapter and allows
host computers designed for RS232 or IEEE 488 bu s communicat ion to contro l the MAT via
the IEEE 11 1 8 bus.
e. The MAT Power Module can also be directly controlled via the key pad of the MBT Series
(“G” Option) Power Sup ply via the IEEE 11 18 bus.
An impor tant feat ure of the MA T Series Power Module is the overvoltage and ov ercurrent pro-
tection circuits . This protection i s provided by two autotracking amplifiers t hat have an overvo lt-
age and overc urrent tracking range of 10% ± 3% of the nom inal values above the prog rammed
Power Module output voltage or current (e.g., for 55 V MAT which has been pr ogrammed to 2V ,
the overvoltage wil l trip at 7.5 V (5.5V, 10% of nominal + 2V , programmed) .
The MAT ser ies Power Modules are built in seve ral mechanical s izes according to their approx-
imate output power rating 1/3 Rack, 2/3 Rack and Full Rack (see Mechanical Outline Drawin g of
the Power Module Ch assis, Figure 1-2) .
Power transis tors and drivers on all Po wer Module designs are mounted on high ly efficient pat-
ented heat sink assemblies t hat are cooled by fans.
MA T 1/3 and 2/3 Rac k size modules are des igned to operate in eith er one of two housings
called RA 50 and RA 51. RA 50 is 5-1/4" x 19" x 25" and acc epts up to three 1/3 Rack Power
Modules. RA 51 is similarly sized, but config ured for one 1/3 Rack Module and one 2/3 Rack
Module. Full Rack MAT Power Modules mount directly into a standard 19 inch Equipment Rack.
