Servotech Power Systems Private Limited

UPS1 & UPS2 are paralleled together through a paralleling unit. The output load is given through the master UPS under healthy conditions. Both the UPS systems are synchronized with bypass. Upon failure of UPS1, the load is taken care off by UPS2 & vice versa. The bypass static switch is enabled only when the both UPS systems fail, providing immediate power to load. The batteries are independently charged through their respective rectifiers.


Truth Table:

B	Static Switch	Result
UPS1 & 2 healthy	OFF	load is given through the master UPS
UPS1 healthy & UPS2 trip	OFF	UPS1 handles entire load
UPS2 healthy & UPS1 trip	OFF	UPS2 handles entire load
UPS1 & 2 trip	ON	Load works on Bypass

Telecom grade inverters operate on 48v dc. These telecom grade inverters are designed for the telecom applications. The telecom grade inverter meets stringent needs of EMI/EMC interferences, required in telecom environment. It is required for telecom application where fixed DC input power supply of -48 DC is continuously available from exchange battery.

Salient features of the telecom grade inverters are as follows-

• High dc to ac conversion efficiency even at lower 48v dc input voltage.
• Instantaneous sine wave control.
• Range: 1kva-20kva.

TECHNICAL SPECIFICATIONS

Input voltage	required for the inverter is (–) 48 volt DC. The DC supply is supplied by the client through exchange battery and hence battery & charger unit is NOT required in the inverter.
Output Voltage	is 230 Volt AC with 3% variation.
Output Frequency	is 50 Hz. with 2 % variation.
Waveform	pure sine-wave with THD < 3% (Total Harmonic Distortion).
Auto Search facility	The inverter shut off the load if the load is more than its rated output & keeps searching for its correctness after every 10 Sec. The inverter is switch-on automatically once the load is within the rated output.
Short Circuit protection	feature is present in the inverter.
