Single-phase Electronic Multi-rate Watt Hour Meter
Detailed Product Description
Single-phase Electronic Multi-rate Watt Hour Meter
A full electronic energy meter to measure the active power in single-phase AC power grids at 50Hz or 60Hz.
Function and Features:
(1). Use imported measuring chips with high accuracy, which can measure the two-way active energy in the single-phase grids.
(2). Rate period function: It has 3 rates of peak, flat and valley and 12 periods. The periods can be set according to the users requirement.
(3). Clock function: It has the hardware clock circuit. The clock erroer is better than 0.5 seconds/day with good temperature coeffient. It has the callendar, week, public holliday and leap year change function. When the power is cut in the grid, the clock is maintained by the internal battery. It also has the function of correcting the time.
(4). Event recording function:It can record the programming time,the date and time of the last programming, times of the power-off in the accessory power suplly, the accumulated time of the powerr-off, and the starting and ending time of each power-off.
(5) Communication function: It has the function of infrared radiation or RS485 communication.
(6). Pre-set function: The customer can use the laptop and PC to preset the needed parameters.
(7) Function of programming password protection.
