787-875 WAGO UPS (DC)

Wago 787-875 is an Uninterruptible Power Supply (UPS) unit designed for DC/DC applications, capable of parallel operation with up to three battery modules for extended buffer time, although temperature measurement evaluation is possible through only one battery module. It operates on a supply voltage of 22-29Vdc (24V nominal) and does not require an AC supply voltage, with a rated current of 20A. This UPS features push-in CAGE CLAMP spring connections for easy installation and is designed to work within an ambient air temperature range for operation of -10°C to +60°C and for storage from -25°C to +85°C. It has an IP20 degree of protection and a control voltage specification that supports a T 25A internal fuse and a typical current limitation function of 1.1...1.3 x Io nom. The UPS dimensions are H171mm x W57mm x D163mm, and it is designed for mounting on a DIN-35 rail. The product is set to be replaced by models supporting 24Vdc and 20-25.5Vdc (battery operation) with a response time that includes a no-load current of 0.1A, a charging current of 1.5A, and a maximum current of 21.5A. It is designed to operate within a humidity range of 5-96% RH without condensation.
