UPS Uninterruptable AC/DC Power Supply TSPC-240UPS Series

◆ Compact universal power supply for

uniterruptable 24 VDC output voltage

◆ Battery protection for over voltage,

deep discharge, short circuit and

reverse connection

◆ Alarm outputs for input, output and

battery condition

◆ Remote On/Off for UPS function and

power supply

◆ Controlled end of charge voltage by

battery temperature sensor

◆ International safety approval package

◆ Suitable for various external 12 VDC

lead acid batteries

* Maximum current at nominal Vout

This power supply provides an integrated professional battery management system

to charge and monitor an external lead-acid battery. The result is a complete DC-

UPS system in a compact housing with no additional parts needed. The external

connected 12 V battery will be charged and held in charged mode by the power

supply. In the event of a mains power failure the battery will supply the output po-

wer until the battery is discharged. To avoid overcharging the battery, an external

temperature sensor adjusts the battery voltage automatically to the required end

of charge voltage. This can extend the battery life. The battery is protected against

deep discharge. Mains power and battery status are monitored regularly and failu-

res indicated by corresponding LED’s and alarm outputs. The module also provides

an external On/Off input to switch-off both, power supply and battery.

TSPC-240UPS Series Function Specification Function Diagram: General Description This power supply is supplied by mains voltage and contains an integrated DC uninterruptible power supply feed by an external battery. It is designed to supply the applied load continuously and without interruption, even when the mains power fails. In this case, the energy is supplied from an external 12V battery to provide the required output voltage.

TSPC-240UPS Series Function Specification (continued) Signals Following signals are made available as LED indicators and corresponding isolated relay contacts: AC-OK Indicates if the input AC voltage is present. During operation outside the DC specification (overload), at low input AC levels (below nominal range) it can be OFF. It will indicate that the battery operation has started in order to maintain the output voltage at 24V level.

TSPC-240UPS Series Function Specification (continued) Remote On/Off The TSPC-240UPS module provides a Battery Remote on/off input (2 pins on signalconnector); if this input is short circuited (switch closed in Fig. 3) the battery will be disconnected from the unit by means of an internal relay. A voltage of 0.5V or less across the Battery Remote on/off terminals will disconnect the battery from the unit.
