The new ultracapacitor-based UPS provides a long lifetime, including at high ambient temperatures, thereby ensuring increased safety in 24 V networks. Uninterrupted power supplies of up to 20 A are available in the event of a power failure with the basic module. The flexible expansion options mean that the output current can be increased to up to 40 A and the buffer time scaled accordingly to meet requirements by adding further capacity modules. All relevant data can be accessed at any time via an isolated USB interface.
