Product Details
Single-phase Two-wire DIN rail kwh panel Meter
1.APLLICATION :
DDM30C single phase two wire electronic DIN-rail active energy meter.
The meter is used to measure 50Hz or 60Hz active energy consumption from single phase two wire AC electricity net.
The features of small size and DIN-rail mounting make it suitable for installation in distribution boards and small standard enclosures.
The meter is widely used in the office buildings, shopping malls, residences, airports and metro,etc.
2.FUNCTIONS AND FEATURES:
35mm standard DIN rail installation or front board setting, complying with standard DIN EN50022.
Single pole width.
LCD 6+1 digits display (999999.1kWh) by without backlight source common LCD.May select white backlight
source LCD display, or clients defined.
Standard configuration one port of pulse output passive (polarity),may select increase a distant port of pulse output passive (nonpolarity),complying with standard IEC62053-31 and DIN43864.
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, high overload, do not need to calibrate for long-term operation.
Directly connect operation.
Standard configuration short terminal cover, which is helpful to reduce installation space and make it convenient to install.May select extended terminal cover, which is for protecting the safety of using electricity.
