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. If the Battery Remote On/Off signal is set to off (short bet-
ween pins) this will not affect the output of the unit in normal mode, however the battery will be disconnected, hence it will not charge.
If the unit enters buffer mode while the Battery Remote On/Off signal is off, the battery will remain disconnected, hence no energy will
be supplied to the load.
Ambient temperature and power rating
The module operates at temperatures between –10ºC and +60ºC, with a minimum start-up temperature of –25ºC. In normal mode the
module can deliver full power up to 60ºC. The boost current of 12A is available at ambient temperatures up to 50ºC with a derating
of 1.67%/°C for temperatures above 50°C, as shown in Fig. 4. In buffer mode the module can deliver full power up to 60ºC with the
boost current of 12A available at ambient temperatures up to 40ºC as shown in Fig. 5.
