PULS UB40.241 uninterruptable power supply

The UB40.241 from PULS is the latest addition to its range of 24 VDC uninterruptable power supplies. The UB40.241 has the highest output current and largest battery size in the range. A maximum continuous output current of 50 A (below 50°C) and up to 60 A for 5s burst and maximum battery size of 200 Ah provides for higher power and longer buffer times. At a constant load of 20 A the buffer time would be over 10 h and at constant 5 A the buffer time would be nearly 2 days.

The UB40.241 uses the 1-battery concept where each 12 V battery is charged and monitored separately, so that matching of batteries is not necessary. A battery size selection switch enables optimising for system battery size, and the temperature-controlled charging extends battery service life. A selectable buffer limit timer can be tuned to specific requirements to disable buffering after the set period in order to reduce recharge times and further extend battery service life. Diagnostic and monitoring functions and dry contact status outputs can be connected to a PLC or to local indicators for early warning. An inhibit input can also be used to prevent system buffering during servicing or other requirements.

Multiple UB40.241 units can also be arranged in various architectures to allow for increased voltage, higher current or to create a redundant UPS system. Designed for industrial applications, the UB40.241 is DIN rail mounted and has an operating temperature range of -25 to 70°C.
