EM524027 SGC code STS Prepayment 3 Phase 4-wire static communicating intelligent Smart electrical energy meters

1. Brief introduction

EM524027 is a 3 Phase 4 Wires meter and it is a STS meter. It has IR Communication 1107 Protocol for meter reading and firmware upgrade. The prepayment function allow users to ‘pay as you go’. The built-in relay can trip when overload or cover opened.As a STS meter, it can save last 50 times recharges’ information and corresponding token. It can also be used for energy quality analysis.

2. Function description

(1) External CT for measurement and circuit protection

(2) Infrared Communication 1107 Protocol, IR for firmware upgrade, RF communication optional

(3) STS Approved,Operate in STS prepayment and post-payment mode

(4) Prepayment via token

(5) Built-in relay trip when overload

(6) Credit and balance alarm

(7) Measurement of significant reverse energy (SRE)

(8) Meter can save the record of last 50 recharge and corresponding token for inquiry

(9) Anti-tamper (anti-fraud) through open cover detection
