Welcome Description The PCU-2100 Load Sharing Redundant Power Supply is a 2U rack-mounted power supply system for Control Matrix field paging components. The PCU-2100 is designed to provide redundant or passive operation from its two independent power supply modules, or “banks”. Each bank is capable of simultaneously powering up to eight Control Matrix PCU Series stations and ten remote control panels. Each bank is an fully independent power supply, internally protected against load faults.
PCU 2100 Integrator’s Manual Front Panel Features 1 2 3 4 5 6 2 2 4 5 6 1. REDUNDANT MODE LED Single color LED (Yellow) indicates that the PCU 2100 is operating in Redundant Mode. If the unit is operating in Dual Mode, this LED will not be illuminated. 2. ACTIVE LED Single-color blue LED indicates the presence of primary power for the supply bank. When the LED is illuminated, the supply bank is ON. 3. DC STATUS LED Single-color (Green) LEDs display status for each supply voltage.

BANK “B” PRIMARY FUSE AC fuse protects the bank B primary power supply. 3. BANK “A” PRIMARY FUSE AC fuse protects the bank A primary power supply. 4. RS-485 IN CONNECTIONS Removable Euro connectors for terminating data lines from COntrolMatrix field devices.
PCU 2100 Integrator’s Manual Connections The circuits of the PCU 2100 are terminated using removable Euro connector blocks for three types of connections: • Bi-polar (three-pin) DC power for PCU Series paging stations • Single-ended (two-pin) DC power for remote control panels • Fault Contacts (three-pin) Each connection requires termination to a removable Euro block (included) that plugs into a mating connector header on the rear panel.
Operation Operational Modes Once the loads are properly terminated, the only operational consideration is whether to configure the PCU 2100 for Dual Mode or Redundant Mode operation. A rear panel switch provides the selection, and a front panel LED indicates operating mode. DUAL MODE Dual Mode operation configures both banks of the PCU 2100 to operate as independent power supply systems. In this mode, all output circuits are fully active on each bank and available for simultaneous use.
PCU 2100 Integrator’s Manual Protection The PCU 2100 includes integral supervisory and protection features designed to provide seamless, stable operation. Each power supply output circuit is protected by a self-resetting fuse. In case of an overload or short, the circuit will shut down until the condition is removed. For the bi-polar supplies, the positive and negative outputs are supervised in tandem.
