The STD18-D signle phase rail energy meter is newly designed, compared with the older rail energy meter, the new one is smaller and more exquisite, which means one electricity box can accommodate more electricity meter. STD18-D is an STS standard compliant, complies with the design standard of international IEC62053-21/23 and international IEC62055-31. Every energy meter equipped with a Remote Control unit, user can simply input your recharging Token by the Remote Control unit without open the electricity, Which is more convenient and safer. Also, there are LED indicator light to remind the user of the status of the meter.
