DSM228C-04 Single-phase Two-wire Electronic Active Energy Meter(ABS Anti-flaming Casing, LCD Display)

APPLICATION

DSM228C-02 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

♦Front board three fixed installation, the casing is made of anti-flaming ABS material, the terminal block is made of bakelite which is moisture-resistant,fire-retardant,high temperature molded overall.

♦ 5+2 or 6+1digits LCD display. May select cyclometer 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.
