General Description

APS3 and APS6 Series (48V) DC Power Systems

APS dc power systems provide high reliability 48V dc power for wiring closet and other data

and telecommunications equipment. Each power system includes ac/dc rectifier modules, a

supervisory module to provide control and communications functions, circuit breakers to

protect the output cabling, and output terminals to connect the cables to the dc powered

equipment and optional batteries. Four APS3 and two APS6 dc power system models are

available, as shown on the following three pages.

• APS3-058 – rack-mounted version, without battery option

• APS3-059 – rack-mounted version, with battery option

• APS3-060 – desktop version, without battery option

• APS3-061 – desktop version, with battery option

• APS6-058 – rack-mounted version, without battery option

• APS6-059 – rack-mounted version, with battery option

Input: APS dc power systems can be powered by a wide range of ac sources such as single-

phase, two-phase, three-phase (L-N) and three-phase (L-L). Depending on the nominal

voltage of the ac supply (120V or 240V), the power systems are equipped with either APU48

or APR48 rectifiers. Fused ac sockets (one per rectifier) are available for connecting the power

system to the ac supply.

Output: Eight floating dc outlets are available for connecting equipment power cables to the

APS dc power system. Each dc outlet is protected by a corresponding 6A or 25A load circuit

breaker. Any combination of 6A or 25A rated load circuit breakers (up to a maximum of

eight) can be fitted, depending on customer requirements.

Battery Option: External VRLA 48V batteries can be connected to APS3-059, APS3-061 and

APS6-059 dc power systems to provide backup power during ac outages. The battery float

voltage is temperature compensated.

Access Power Rectifiers

There are three status indicator LEDs on the Access Power Rectifier front panel (Power On,

Urgent Alarm and Non-Urgent Alarm).

Two types of fan-cooled, hot-pluggable Access Power Rectifiers are available:

• APU48 – 48 V, 720 W, 120 - 240 V ac

• APR48 – 48 V, 1500 W, 208 - 240 V ac

SM45 Supervisory Module

The SM45 supervisory module is an advanced control and monitoring solution for Access

Power Solutions (APS) dc power systems. It provides a full suite of advanced

communications options, including built-in Ethernet interface, Web server and SNMP agent.

Alarm notifications may be by SNMP traps. The SM45 has an onboard audible indicator and

two alarm LEDs.
