General information

• Providing guaranteed power supply for communications equipment with DC 48 V voltage in the cases of temporary absence of mains 220 VAC voltage/

• For interruptions of mains power supply it provides power supply for the equipment for 24 hours with load current of up to 0,7 A.

• Range if input AC voltage is from 150 to 290 V.

• Maximum load current 5 A including battery charging current.

• Correction power factor of consumption from AC mains.

• Protection from short circuits and critical discharge voltage of batteries.

• Support of local monitoring via RS-232 interface.

• Support of network monitoring system via RS-485 interface.

• Installation into 19” “euro” cabinet of floor mounted AB-02 cabinet.

Functionalities

• Measuring of mains 220 VAC.

• Measuring of battery charge/discharge current.

• Measuring of load current.

• Disconnecting the load when the current exceeds 5 A and it’s re-connection after lowering the current.

• Measuring of battery viltage.

• Disconnecting the load when battery voltage drops below 44 V.

• Re-connecting the load when the battery voltage rises up above 52 V or when mains 220 VAC re-appears.

• Measuring of rotation speed of built-in cooling fans.

• Measuring of built-in solid-state elements’ heat-sinks temperature, lowering charge current at limit temperature value.

• Indication of mains 220 VAC voltage presence.

• Indication of output 48 VDC voltage presence.

• Indication of charge current presence (green LED) and discharge current presence (red LED).
