Ultracapacitor and battery-powered DC UPS

BLOCK, specialists in power supply interfacing, has announced the introduction of two 24V/40A uninterruptible power supplies. These DC input UPS are designed to offer reliable availability of safety-critical systems in the case of power failure. BLOCK UPS supports 12V, 24V and 48V systems and can be either battery-powered or use capacitive energy storage.

Product selection will depend on the application. The battery-powered UPS supports various established battery technologies and provides immediate system back-up in the event of a power failure. Hold-up time may be adjusted to meet end user requirements by adding extra battery packs.

The capacitive energy storage UPS uses state-of-the-art, high efficiency, long life ultracapacitors and provides system power support up to the minute range.

Due to the long service life of ultracapacitors and the internal temperature-controlled battery management system, BLOCK says maintenance costs during operation are reduced to a minimum. It adds that the capacitive UPS is easy to expand by adding capacitive modules, offers a high power density, is maintenance-free, and also offers parameter setting via USB interface and rotary switch.

The communication features of both modules are designed to provide integrated monitoring of the entire system, in line with the requirements of Industry 4.0.

Parameterisation of the both types of UPS is possible using BLOCK’s UPS Control Software either via the front panel mounted rotary switch or via the USB interface. The USB port on both versions is also shock and vibration-proofed.

BLOCK says 5A charging current has been added to ensure fast availability, other features also include battery start-up without mains power, parameter setting via interface, and rotary switch.
