Battery-backed IPS

The RCM-W2-AB is a two-channel, all-current-sensitive residual current meter for monitoring main distribution boards up to a maximum residual current of 20 A.

In conjunction with approved residual current transformers, the RCM-W2-AB is used to measure and monitor residual currents in TN and TT systems.

Together with other devices in the RCM series, as well as display devices or devices for data coupling to external systems, it forms a complete differential and operating current monitoring system. This monitoring system increases the operational safety of your systems. For example, faults or the occurrence of a (usually gradual) increase in differential currents are detected at an early stage, enabling preventive maintenance.

In building main distributions, our transfer switching device of type UEGL reliably ensures the changeover between the preferred supply and the secondary supply line (according DIN VDE 0100-710). It complies with all normative requirements, e.g. with regard to:

• Voltage monitoring of both supply lines as well as the outgoing line
• Automatic transfer to the secondary supply line in case of failure of the preferred supply
• Automatic retransfer to the preferred supply
• Configurable transfer times
• Control functions with single-fault safety
• Indication/notification of operational readiness and faults
• Possibility of on-site functional testing

The CPM-W20 power and consumption monitoring device is used to measure and calculate electrical quantities in industrial and public power supply networks.

Product features
