GENERAL
DDS228 Single-phase Static Energy Meter is used to measure 50Hz or 60Hz active energy consumption from single phase AC electricity net.
The meter adopts LSI (Large-scale Integration) and SMTmanufacturing technique, the key components and part all adopt long life type.
With the features of good reliability, small volume, light weight, specious appearance, etc., the meter is widely used in office buildings, shopping malls, residences, airports and metro, etc.
FEATURES AND FUNCTIONS
1. Front board three fixed installation, the casing is made of high definition material such as ABS anti-flaming material, PC etc., and the terminal is made of bakelite which is moisture-resistant, fire-retardant, high temperature molded overall.
2.5+1 or 6+1 digits cyclometer display, (Entirely closed register, HF magnet immune register, unidirectional step motor type impulse register optional). May select LCD display. (Standard LCD, or backlight LCD, can select a maintenance-free lithium battery, used to display when power failure. )
3. 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.
4. LED instructions power supply state, signal of energy impulse
5. Single direction measures single phase two wire active power consumption. May select to measure single phase three wire. It is nothing with direction of the flow of load current, complying with standard IEC62053-21, IEC62052-11.
6. Adopts high reliable and long-life electric components, hioverload, do not need to calibrate for long-term operation
7. Direct connect operation, there are two types wiring you may select.
8. Extended or short terminal cover.
Other Optional Functions
1. Reverse indicator: An LED indicator will be on when the current is reversed
2. Anti-tamper, when load is connected between the line and the earth
3. Max demand (kW) display
