PWR 30 Modular Switched Mode Rectifier System PWR 30 The PWR 30 is a compact, state-of-the-art rectifier system designed for today’s space restricted communications applications. PWR 30 rectifier systems are designed to provide the ultimate in flexibility and modularity. Each rectifier system PWR 30 can accommodate up to three power modules APC TWF0500 9A/54,5VDC in only 4 rack units of space. In addition to allowing hot plug-in modules, the PWR 30 provides front access for ease of installation, maintenance and upgrading. The available output voltages are ideal for the telecommunication and data communication markets. FEATURES Rectifiers deliver steady power output of 27A at 54,5 VDC with UI characteristic. Current limit and overvoltage protection, power factor corrected, universal input. Integral fan cooling, thermal protection. Full internal computer control, parallel current share. Extremely durable, cost-effective rectifiers ideally suited for small power applications. Front access, hot plug-in modules, true N+1 redundancy. Multiple modules may be utilized to provide additional capacity. Front panel includes status LED’s, separate volt and amp meters, AC input circuit breaker, DC output circuit breaker and battery circuit breaker. AC inputs and DC outputs are on rear panel of rack enclosure. Cabinet alarms are provided in the form of change-over relay contacts: System Healthy, AC Healthy, Rectifier 1,2,3 fail, AC input breaker, DC output breaker, Battery breaker, Low system voltage, Battery switched off. Automatic battery disconnect point is set to 42V+/-0.05V. 1 of 3 PWR 30 ACCESSORIES For request of customer is possible to provide PWR 30 monitoring interface include functions : The temperature-controlled battery-charging voltage and operating voltage. RS232 interface. Ethernet interface or CAN Bus For remote control via Telecommunication Management Network there are functions: Equalize charge mode switch. Float charge mode switch. Obstruction of battery test running. Rectifier switch ON/OFF. The following alarms are transmitted by the control module via TMN : Rectifier fault (internal fault) per module AC power outage. Circuit breaker outage. Battery voltage. Disconnection of the load from the battery in 3 min after this alarm. Disconnection of the load. Battery test running detection of battery capacity Data of battery from EEPROM SPECIFICATIONS ELECTRICAL INPUT Input Voltage: 85 – 264 V AC 47 – 63 Hz Supply type: single phase TN – S systems Input Current: 6A maximum at 115V input / module 3A maximum at 230V input, 500W output / module Power Factor: Typically 0.99 Efficiency: 83% including series output diode OUTPUT Nominal output Voltage: 54.5V Output current: 9A per one module, max. 27A Temperature range: 0 to +50°C operating ( to +65°C with output derating) POWER: 500W per one module, max. 1500W continuous up to the maximum rated temperature Output noise: 0-500kHz noise peak to peak 50mV 500kHz-300MHz noise peak to peak 150mV Psonometric noise 2mV(32dBrnc) 2 of 3 PWR 30 PROTECTION Input curcuit breaker: 16A, Curve „C“ Output current limit: The units are designed to operate continuously in current limit for battery charging purposes. the characteristic is constant current and is set to 105% ±5% of IMAX. Output overvoltage: Output overvoltage is adjustable 50- 60V on 54V units. Set 60V ±5% on 54V units. Overtemperature: Under extreme conditions, the output power will be inhibited until the temperature drops to normal operating levels. INDICATORS Power supply OK: Power supply is in the normal operation. Units ERROR: One or more units are fault, The internal fan in the unit(s) is fail, Overvoltage, Overtemperature AC error: AC input voltage is fault Low voltage warning: This light is on, when the power supply is running in the battery mode and the battery voltage is less than 45.5V±0.05V Load disconnect: The light is on, when the power supply is running in the battery mode and output load is disconnect. The Battery voltage is less than 42.0V±0.05V. Memory: There are four memory lights with the same functions as the main lights. They are set, when the main lamp is set on. Memory is reseting by the button on the front panel.
