UMG 96-PA-CH 90...277 V AC, 90...250 V DC

3-in-1 energy management: | power quality monitoring | RCM monitoring.

The UMG 96-PA energy measurement device can combine four functions in one device and can be modularly extended by two analog inputs - either as 0-20 mA analog inputs (e.g. DC measurement) or as RCM measurement inputs with cable break detection and additional temperature measurement:

Energy management system

- Continuous energy monitoring

- Identification of potential savings

- Reduction of energy costs

- Compliance with tax and regulatory requirements

Power quality

- Secure, highly available power supply

- Avoidance of production downtime

- Maximize uptime / preventive maintenance

- Avoidance of quality defects in the product

Residual current monitoring (RCM)

- Permanent monitoring of residual currents

- Supports fire and personal protection

- Reduced effort for DGUV V3 testing

- Increased system availability
