Applications

The HWM052 series are advanced front panel mounted single phase electronic active energy meters. Their designs are based on the well-known model HWM051 series, fully absorbing thenew technologies of electronic meters from home and abroad. 1 Their technical performancescompletely conform to International Standards IEC 62053-21 for Class 1 single phase active energy meter. They can directly and accurately measure the load active energy consumption in the single phase AC networks of rated frequency 50Hz or 60Hz and used indoors or in the meter box outdoors. The LEM052 series have multiple configurations for option, to be suitable with the various market demands. They have features with excellent long-term reliability, small volume, light weight, perfect appearance, easy installation, etc.

◆Can select the step motor impulse register of 5+1 digits (99999.1kWh) or 6+1 digits (99999. 1kWh) LCD display.

◆Can select the maintenance free ithium battery inside for LCD display to read the meter while the power is cut.

◆Equipped with a polarity passive energy impulse output terminal, conforming to Standards IEC 62053–31 and DIN 43864.

◆LEDs indicate the power state (green) and the energy impulse signal (red).

◆Automatic detection for the load current flow direction and will be indicated by LED.

◆Measure the active energy consumption in one direction on single phase two wire or single phase three wire, which is not related with the load current flow direction at all, complying with Standards IEC 62053-21.

◆Direct connection. For single phase two wire, two types of connections: type 1A and type 1B for option. For single phase three wire, the connection is type 2A.

◆Can select the extended terminal cover or shot terminal cover.
