1.Brief Introduction

EM124037 is a single phase prepayment meter and it supports Infrared, RS485 and GPRS Communication. The prepayment function allow users ‘pay as you go’. IR and RS485 Communication is always present while GPRS Communication is realized through plug and play module. Users are allowed to choose GPRS module from standard of 2G,3G,4G and 5G.

Through token&keypad or GPRS, users can recharge directly or remotely. The built-in 120A latching relay will disconnect when overload or credit exhaustion and the overload protection function is programmable.

EM124037’s data encryption process complies with international standard IEC62052-11, IEC 62053 -21. This meter also has KEMA certificate.
