PSC-17C 17 Amp Power Supply

INTRODUCTION The Model PSC-17C from Siemens Industry, Inc. is a high current power supply that

provides the Fire Alarm system (Sprachalarmsystem E100) with primary regulated 24

VDC. It is rated at 17 A and has a built-in charger that is capable of charging up to 100

Ah batteries. It also has a microprocessor-controlled transfer circuit that allows the

PSC-17C to switch the system power to stand-by batteries during loss or reduction of

AC power.

The PSC-17C incorporates a 24 A

circuit breaker on the battery input.

The PSC-17C communicates

directly to the PMI-S to report

fault conditions and allows the

PMI-S to query the status of

the power supply. It has one

common trouble relay and

two programmable relays. The

common trouble relay is

defaulted to activate when

communication between DAC

and PMI or DAC and power

supply is lost.

The PSC-17C mounts at the

back of the enclosure of the

E100 system and occupies

1/4 of the E100 Mounting

Plate MP-M.

Features The PSC-17C features are as follows:

• Universal AC power input 120 VAC - 240 VAC @ 50 Hz / 60 Hz

• Off-line Switch Mode Power Converter

• Power Factor Correction

• Built-in Battery Charger

• Total Output power of 17 A @ 24 VDC

• Two separate power output terminals: one power limited terminal with 4 A

max @ 24 VDC capacity and one non-power limited terminal with 17 A @ 24

VDC capacity (total not to exceed 17 A)

Installation Instructions Model PSC-17C 17 Amp Power Supply INTRODUCTION The Model PSC-17C from Siemens Industry, Inc. is a high current power supply that provides the Fire Alarm system (Sprachalarmsystem E100) with primary regulated 24 VDC. It is rated at 17 A and has a built-in charger that is capable of charging up to 100 Ah batteries. It also has a microprocessor-controlled transfer circuit that allows the PSC-17C to switch the system power to stand-by batteries during loss or reduction of AC power.

OPERATION • AC Input Supervision with Battery Back-up: In the event of reduction or cut off of AC power, the microprocessor controller transfer circuit will switch the system power to stand-by batteries. • Both output terminals have current measurement capability • Auto resettable current protection circuits for overload and short circuit • Access to CC-5/CC-2 System bus • Supplies 6.2 VDC @ 2 A max. (power limited) to the system bus • Supplies 24 VDC @ 2 A max.

ENABLE • P10: Set P10 jumper for ground fault supervision. For systems with multiple PSC-17Cs in a single enclosure, ground fault supervision must be enabled on only one PSC-17C. Set the jumper on P10 to the DISABLE or right-hand position on all but one PSC-17C. • P13: Set P13 jumper to select type of battery being used.

Use the ferrites provided on all cables as shown in Figures 8 and 9. All cables are to be wrapped around the ferrites once and the two battery wires are to be braided together. The PSC-17C has removable terminal blocks and connectors at the top and bottom of the module. The terminals and connectors at the top of the PSC-17C are power limited. The terminals and connectors at the bottom of the PSC-17C are non-power limited. (Refer to Figure 7.
