Summary:
    DT580 series 3-phase inductive long-life active meters are manufactured according to the requirements of the Mechanical & Electricity Ministry and meet the IEC521 standard.

Technical Specification:
◆ Accuracy: class 1.0&2.0
◆ Frequency:50Hz, 60Hz
◆ Voltage:220-240V
◆ Current(A): 1.5(6), 2.5(10), 5(20), 5(30), 10(40), 10(60), 15(60), 20(80), 30(100)
◆ Driving torque:＞8g.cm
◆ Voltage power loss :＜1w
◆ Starting current:＜0.5%Ib

Features:
◆ Service life: not ＜25 years
◆ Wide load: 4x-6x current load
◆ Stable error curve
◆ Low power loss
◆ Anti-tamper protection:
    1. Records forward and reverse accumulated energy with anti-tamper reverse load protection.
    2. The meter design features a back mounted fastener which means the case must be broken if the meter is tampered with.
    3. An extended terminal cover prevents external short circuit; if the neutral connection is removed load current will not flow back to the meter.
◆ Magnetic bearing: high sensitivity, high stability and long life
◆ The meter case is a strong polycarbonate construction with high insulating properties
◆ Meter reading system employs preset impulse output
◆ No adjustment for anti-creep hole
◆ Voltage and current components are secured using high accuracy rivet technology perfect conformability
◆ Epoxy resin coated voltage coil provides high insulation properties for 30 year even under adverse environmental conditions

Materials:
◆ Magnetic bearing:
    1. Permanent coercive force ALNICO magnetic-steel, stable magnetic process, high stability
    2. Precision graphite sleeve, perfect self-lubricating, low friction, wear resistance
◆ Voltage and current sores are manufactured from high quality and low linear loss silicon steel for high-stability
◆ Brake magnetic steel: ALNICO37multi-pole,good stability
◆ Low friction polyacetal drum register and bearing bush, wear resistance, perfect self-lubricating.
