Rectifier and Battery Power Systems

The LORAIN ® A8CAB/BD power system is comprised of a modular lightweight -48 VDC, 2-8 amp rectifier cabinet with optional battery cabinets. Systems can be specified in a variety of configurations to suit your specific power requirements.

Lorain ® A8CAB/BD Power System

The rectifier cabinet is arranged to accept up to four 2 amp rectifier modules that supply 48 VDC load current while float charging a standby battery. If commercial power fails, the battery immediately supplies load current. Six GMT fuse positions are provided for individual load protection. Local and remote indicators provide status for AC, rectifiers, load and battery. The cabinet is equipped with an IEC 320 socket arranged for 120/220 VAC 50/60 HZ commercial power.

Battery cabinets can be specified in 7 or 12 amp hour capacities. Multiple or larger batteries can be provided where longer reserve times are required. Each battery is protected by an internal fuse and a low voltage disconnect is included to protect battery and load.

Lorain ® A8CAB/BD Battery Cabinet

Units are designed to mount adjacent to the equipment being powered, and connectorized cables can be supplied to simplify on-site installation.

Features & Benefits

• Modular Design—easy to configure, maintain and expand
• Compact, Lightweight Cabinets—permits one person installation in limited space
• Temperature Hardened—dependable operation in harsh environments
• Low Voltage Disconnect—provides complete load and battery protection
• Wall or Rack Mounting—adaptable to all types of site configurations
• Optional Batteries—covers a wide range of loads and reserve times
• Local and Remote Alarms—continuously monitors complete system status

Application

The A8CAB power system is comprised of a modular lightweight -48VDC, 2-8 Amp rectifier cabinet with optional battery cabinets. Systems can be specified in a variety of configurations to suit your specific power requirements. The rectifier cabinet is arranged to accept up to (4) 2-amp rectifier modules that supply 48 VDC load current while float charging a standby battery. The cabinet is equipped with an IEC 320 socket arranged for 120/220 VAC, 50/60 Hz commercial power.

Battery cabinets can be specified in 7 or 12 amp hour capacities. Multiple or larger batteries can be provided where longer reserve times are required. Units are designed to mount adjacent to the equipment being powered and connectorized cables can be supplied to simplify on-site installation.

The A8CAB is designed to supply primary or backup DC power to communications equipment installed in remote cabinets or on customer's premises. Specific applications include: microwave PBX, key systems, multiplexers, PCS equipment, xDSL products, Routers, FITL electronics and alarm or security circuits.
