Operation
The Model PS-35 stepdown transformer and bridge from
Siemens Industry, Inc. provides a rectified, full wave 24
VDC output from an input supply of 120 VAC, 50/60 Hz.
The input power consists of a main phase, with an inde-
pendent circuitbreaker labeled Reset, and a trouble
phase, which is separately fused. Both inputs use a com-
mon neutral.
The 24 volt full wave output is rated at 9 amperes DC, full
load, and 6 amperes DC, standby load. Separate output
fuses are provided for both the main and
auxiliary power outputs, fused at 15 amps and 2 amps,
respectively.
Terminals 5 and 6 provide 1.5A auxiliary output when the
PS-35 is used as a CP-35 system supply. For example,
output is rated 24 VDC, 1.5A max for internal applications
such as SR-32, SR-33, or Model RA annunciator located
within control unit enclosure(s).
When used as a separate 24 VDC power supply with bat-
tery backup and jumper plug JP-PS, terminals 5 and 6
may provide the full 9A loading. Typical wiring when used
with the TC-30U is shown in the illustration on the back of
this sheet.
Surge protection is provided across both the input
phases as well as the DC output.
Installation
When Used as Power Supply for Control Panel CP-35:
1. Mount the module to the horizontal mounting
brackets in upper right-hand position, on the top row
of the control enclosure.
2. Install wiring as necessary. Use special plug and
harness assembly for connection to CP-35
Control Panel. Refer to CP-35 Wiring Diagram (315-
084902) in the Control Panel INSTALLATION AND
MAINTENANCE INSTRUCTIONS for system inter-
connections.
3. Install protection cover plate over the terminals
after making wiring connections.
When Used as 24 VDC Power Supply with Battery Backup:
(See TYPICAL WIRING DIAGRAM illustration on reverse.)
1. Mount the module to the horizontal mounting
brackets in the control enclosure. Select a
convenient location so that wiring runs are as short
as possible. Note that the PS-35 occupies three
module positions.
2. Connect wiring as necessary.
Note: When an additional PS-35 Power Supply with
jumper plug JP-PS is used for extra bell ringing
capability in a CP-35 controlled system with
emergency power, a transfer module Model
TC-30U is required to supply emergency power
to the audible signal circuit. When battery
backup is not provided, the PS-35 output should
be supervised (SR-30 or equal).
3. Install protection cover plate over the terminals
after making wiring connections.
Fuse Replacement
Remove all system power before replacing fuses, first
battery and then AC. To power up, connect AC first then
battery.
PS-35:
For fuses F2 and F3, slide fuse off fuse holders, then
snap in new fuses.
F2: P/N 105-224090, 15A @ 250V max
F3: P/N 105-284845, 2A @ 125V max
TC-30U:
Push in and turn counterclockwise. Remove fuse from cap.
Replace with P/N 105-224090, 15A @ 250V max.
