DSM228-04 Single-phase Two-wire Electronic Active Energy Meter(ABS Anti-flaming Casing, Long Terminal Cover, Cyclometer Display)

APPLICATION

DSM228-04 single phase two wire electronic active energy meter.

The meter is used to measure 50Hz or 60Hz active energy consumption from single phase two wire AC electricity net.

The meter adopts LSI (Large-scale Integration) and SMTmanufacturing technique,the key components of

which all adopt long life type.

With the features of good reliability, small volume, light weight, specious appearance, etc., it is widely used in office

buildings, shopping malls, residences, airports and metro,etc.

FUNCTIONS AND FEATURES

♦5+1 or 6+1 digits cyclometer display, (Entirely closed register, HF magnet immune register, unidirectional step

motor type impulse register optional) . May select LED or LCD display

♦Standard configuration one port of pulse output passive (polarity),may select increase a distant port of pulse

output passive(nonpolarity),complying with standard IEC62053-21.

♦Single direction measures single phase two wire active power consumption. It is nothing with direction of

the flow of load

current,complying with standard IEC62053-21,IEC62052-11.

♦Adopts high reliable and long-life electric components,hioverload, do not need to calibrate for long-term operation

♦Direct connect operation,there are two types wiring you may select.

♦Extended terminal cover,which is for protecting the safety of using electricity.
