General Information
The Model 12598-004 Redundant 48 V DC Module is designed to accept the outputs of two 48 V dc
power supplies while providing a single dc output. This module will typically be used in custom
products, namely ADVANCE cabinets requiring redundant circuits to meet various agency requirements.

Hardware Configuration
The Model 12598-004 Redundant 48 V dc Module consists of a single-sided printed circuit board
measuring 4.0 L 4.0 W 1.5 H inches (102 102 38.1 mm). It is equipped with two 15A rated
diodes each mounted to a heat sink, two small DPDT relays to provide dry contact status outputs for each
power supply, and four modular (plug-in type) terminal blocks.
Installation
CAUTION
When installing or replacing this module, be sure to disconnect power for
safety.
The Model 12598-004 Module is designed for chassis mounting or on 4-inch Snap Trak
inserting the module in SnapTrak
, exercise care when pressing the module edges into the SnapTrak to
. When
avoid damage to the module’s printed circuit board and components.
Once installed in the SnapTrak
, be sure the module edges are secured in the channels so that the module
does not dislodge during transport or operation if subjected to vibration. Also, if this module is used with
other modules in the SnapTrak
, be sure to leave spacing between modules to facilitate wiring at any
edge-mounted terminal blocks.
Terminations
The Model 12598-004 Redundant 48 V dc Module is equipped with modular (plug-in type) terminal
blocks, which simplify external wire connections during installation, and provide quick disconnect if
replacement is ever require d.
The following is a breakdown of each terminal block and its function(s):
TB1 – is the 48 V dc power input from Power Supply 1 (PS1) to the module.
TB2 – is the 48 V dc power input from Power Supply 2 (PS2) to the module.
TB3 – is the 48 V dc power output from the module to the load.
TB4 – are dry output contacts for the PS1 and PS2 faults respectively. Each connected power supply has
two sets of contacts, which are a Form “C” type. The maximum switching capacity for each contact set is
30 V dc @ 1 amp, and can be used for triggering a remote status indicator or a supervised input at a
system device for visual text display.

Operation
The Model 12598-004 Redundant 48 V DC Module automatically switches to the backup power supply in
the event the primary power supply is lost. After successful installation and testing, it requires no
operator intervention.
Functional Op eration
The Model 12598-004 operates with two 48 V dc power supplies. When 48 V dc power is applied to the
PS1
IN and PS2 IN terminals of the module, relays K1 and K2 become active. Output voltage at the DC
OUT terminals will be approximately 47.4 V to 47.1 V dc, which is due to a voltage drop of approx. 0.6
V to 0.9 V depending on the load current through CR1 and CR2. Thus, as load current increases through
the diodes, the voltage drop across each diode increases toward the maximum value of 0.9 V.
Also, since CR1 or CR2 have a slightly different voltage drops (or turn-on thresholds), either of the
connected power supplies (at PS1
IN or PS2 IN) may initially supply power to load.
Maintenance
The Model 12598-004 Module does not contain any user serviceable parts. Do not attempt to make any
repairs to the module. If the module requires service, contact your Regional Service Center for a return
authorization number (RA#). The module should be shipped prepaid to GAI-Tronics with a return
authorization number and a purchase order number. If the module is under warranty, repairs or a
replacement will be made in accordance with GAI-Tronics’ warranty policy. Please include a written
explanation of all defects to assist our technicians in their troubleshooting efforts.
Call 800-492-1212 inside the USA or 610-777-1374 outside the USA for help identifying the Regional
Service Center closest to you.
Troubleshooting
Problem Solution
Module is damaged. Do not attempt to repair the module.
Contact GAI-Tronics service for repair or replacement of the
module in accordance with the information provided on this page.
Voltage is applied to both inputs,
but voltage is not present at the
output terminals.
All connections and connectors are
properly made, but still no output
voltage.
Relay status contact markings are
incorrect when module is not
powered.
After performing all wiring checks,
trouble-shooting, etc. as described
in this section, the module still does
not function properly.
Verify plug-in connectors at JTB1, JTB2 and JTB3 are properly
inserted.
Verify wiring at each connector has proper polarity.
The relay status contact markings are based on the module being
actively powered (i.e., in an energized state).
Contact GAI-Tronics service for repair or replacement of the
module in accordance with the information provided on this page.
