Relay Control Box

Relay Load Control box for smart grid applications and equipment protection

Product Description

Protect your investment by adding extra relays to your smart meter for complete grid management

Traditionally, energy meters were simple devices that measured power consumption, forming the basis for electricity billing. However, today’s energy meters are taking on much greater responsibilities. Beyond just power measurement, they are now essential tools for power quality monitoring, control, scheduling analysis, and security monitoring. Most electricity meters do not contain switchable relays or do not support remote switching.
