SLR 5000 Series Power Supply

5.1

Description

In this chapter, a general description, performance specifications, and identification of the inputs and

outputs are given for the power supply. The information provided is sufficient to give service personnel

a functional understanding of the module, allowing maintenance and troubleshooting to the module

level. (See SLR 5000 Series Maintenance and Disassembly/Reassembly on page 97 for detailed

removal or installation procedures for all modules in the SLR 5000 series repeater.)

5.1.1

General Description

The power supply, with front-to-rear airflow, operates from either an AC or DC input and provides the

DC operating voltage for the SLR 5000 series repeater. The power supply also provides an integrated

battery charger to maintain the charge on a negatively grounded 12 VDC (nominal) battery system.

Figure 17: Front View of the SLR 5000 Series Power Supply on page 64 displays the front and rear

views of the SLR 5000 series Power Supply.

Additionally, the power supply affords the following performance features:

• Power Factor Correction (PFC) – aids in lowering the ampacity requirements of the AC power

source.

• Over-Voltage Protection (OVP) – lowers the risk of damaging the repeater should input AC or DC

levels approach damaging levels.

• Over-Current Protection (OCP) – aids in preventing a cascaded failure within the repeater.

• Reverse Polarity Protection – aids in preventing damage to the repeater due to installation mishaps.

• Configurable Battery Charger Voltage – tailors the float voltage to your battery manufactures

charging recommendations.

• Configurable Low Voltage Disconnect (LVD) – tailors the battery disconnect voltage to your battery

manufactures recommendations.

• Configurable Power Source Preference – when both AC and DC sources are present (and within

their respective operational bounds), this feature allows one to select the primary power source the

repeater uses.

• Battery Revert – should the AC source be interrupted, this function allows the power supply to

seamlessly transfer to a DC source until the AC source is restored. This results in uninterrupted

radio service for as long as DC power can be provided.

NOTICE: A user supplied external 12 V (nominal) battery system is required to support the

battery backup feature so that when the AC power fails, the SLR 5000 series repeater can

be powered from a DC battery source if it is connected to the PS.

NOTICE: The power supply cooling fan is replaceable and external to the power supply

itself. See SLR 5000 Series Maintenance and Disassembly/Reassembly on page 97 for

replacement details.
