DTSY23/26 Three-phase Prepayment Energy Meter

DTSY23/26 Three-phase Prepayment Energy Meter

Overview

Electronic Three-phase Four-wire Energy Meter (CT Input), Three-phase Three-wire Energy Meter (CT Input) and Three-phase Four-wire Energy Meter (Direct Input) adopt the latest micro-electronic technology to measure three-phase AC active power energy with frequency 50/60Hz,meanwhile fulfill prepayment management function which means paying the expenses firstly, consuming energy afterwards as well as load control function. This series of watt-hour meter has special outside structure and exclusive function features which can suit for different requirements for power consuming

Function

Overdraft can be permitted once under emergency condition, the overdraft amount=Load Gate x 24 Hours. When meter trips at overload or the energy is exhausted, signal will be sent out for external warning facilities to remind customer of purchasing power or reducing load used. Load control can be selected.
(1) Delaying trip at overload and the delay time can be selected freely
(2) No trip at overload but measuring overload energy separately

Applicable Conditions

Working at an ambient temperature -25 ℃ ~ +65 ℃, relative humidity of 85% of the environment

Operating voltage range

Specifications

Maximum Demand Clear
Max Demand can be cleaned by use of Data Collected Card.
Overdraft Function
The selection to the energy overdraft function can be processed according to the requirementof user to realize the overdraft function once when residual energy is less than the warning gate. If no selection, the meter will take as no overdraft.

Pre-warning Output Function By Means of Trip
To make the meter's warning function more effective in reminding user, this meter adds an output return circuit with no battery contacts (AC 220V x 5A/DC 12V x 12A) to realize the output of (1) warning at overload (2) pre-warning at energy deficiency
