800W rectifier power supplies module series PSR308

Due to the modular concept and a high scalability the user is able to equip the power supply with additional modules according to his actual power demand. The chargers are very user-friendly and can be swapped and upgraded during operation.

The devices get their operation parameters via the system wide CAN communication bus. After a successful login a central monitoring unit controls and monitors the devices. In case of CAN bus interruption the modules operate continuously with internal default values. Therefore, the supply of the connected loads and the charging of the batteries are guaranteed without any interception. The nominal output power of the unit is 800W (600W at input voltage ≤173VAC). Up to 6 modules can be integrated in a 19" sub rack with 4U (forced cooling mode with fan rack).

Benefits:

• 1/4x19”, 3U unit
• Single-phase module with sinusoidal input current (PFC)
• Input overvoltage protection
• "Hot-Plug-In" design with backplane connection
• High power density
• CAN-Bus interface
• Integrated decoupling from the DC bus
• Front-to-back airflow with temperature controlled fan cooling
• Suitable for charging Pb- und NiCd-batteries

2700W rectifier power supplies module series PSR327

1800W rectifier power supplies module series PSS18

A constant voltage and current control circuit performs the correction of output voltage deviations caused by transient deviations of the input voltage or load within less than 1.5ms. This permits constant current operation down to continuous short circuit.

A micro controller unit equipped with two control keys and digital displays at the front panel provides permanent monitoring of output voltage, output current and temperature. This feature offers easy adjustment and programming of output parameters and monitoring thresholds.

To increase the output power of the supply system, it is possible to operate the PSS modules in parallel connection. For the control of all parameters and measurement values it is advantageous to use the monitoring device UPC3 which communicates with the modules via CAN–bus interface.

Benfits:

• 1/3x19”, 6U
• Single-phase module with sinusoidal input current
• Frontside connectors
• "Hot-Plug-In" capability
• Active current sharing (optionally)
• CAN-Bus interface
• Temperature compensation of the charging voltage
• Digital display for output voltage, current and adjustment values
• Convection Cooling
• Ability for stand-alone operation

8000W Power supply modules series PSR380

The rectifier can be used in all DC applications with or without battery as a stand-alone unit or in a connection with a central DC controller unit.

Due to the modular concept and a high scalability the user is able to equip the power supply with additional modules according to his actual power profile. The chargers are very user-friendly and can be swapped and upgraded during the operation.

The devices get their operation parameters via the system wide CAN communication bus. After a successful login a central monitoring unit controls and monitors the devices. In case of CAN bus interruption the modules operate continuously with internal default values. Therefore, the supply of the connected loads and the charging of the batteries are guaranteed without any interception.
