CT / 5A 3 Phase Active Din Rail Energy Meter With Pulse Output &
Liquid Crystal Display
Product Description
Din rail energy meter YEM021AC is three phase four wire active
electronic DIN rail active energy meter. The meter adopts up to
date micro-electronics technique and imported special large sacle
intergreated circuit and SMT technology. The meter are completely
conformed to the relative requirements of class 1 three phase
active energy meter stipulated in international standard IEC
62053-21. It can accurately measure 50Hz / 60Hz active energy
consumption from three phase four wire AC electricity net and
display the data by seven digits LCD. The main characteristic of
the meter is that it can be connected with CT. User can set 27
ratios according to his need, and the meter can directly reading
the data without mutiplying the CT rate, making it more
conveniently to read the data.
Specification
Model | Accuracy | Reference Voltage | Current Specification | Starting Current | Insulation Performance |
YEM021AC | Class 1 | 3x127/220V 3x230/400V | CT 5A | 0.01A | AC voltage 4kv for 1 min, 1.2/50us waveform impulse voltage 6kv |
* If you need different reference voltage or current specification,
please advisory our sales personnel.
Competitive Advantage
1. It can choose many kinds of installation way, such as 35mm
standard DIN rail installation, or front board installed (mounting
holes center distance 63 mm), users can choose any one by
themselves.
2. Type S wiring (Inlet from bottom, outlet from top), use CT
connect operation, may select set 27 ratio, after set the meter
will direct reading when read, and haven’t multiplied by rate of
CT.
3. Seven digits display LCD, 5+2 digits display (99999.91 kWh, only
ratio of CT when 5:5 A) or 7digits, it is choose by ratio of CT
which is set.
4. There are a polarity port of pulse output passive closed and a
nonpolarity port of pulse output passive distant (the output rate
is 10 kWh/pulse), ). Complying with standard IEC 62053-31 and DIN
43864.
5. Standard configuration there are a port of far infrared data
communication and a port of RS485 data communication. Communication
agreement complying with standard DL/T645-1997, can also choose
without function of data communication. (Product Configuration code
is NC).
6. Six LED instructions respectively every power supply state,
signal of closed energy impulse and distant energy impulse and data
communication state.
7. Automatic detection the direction of the flow of load current.
And Instructions on individual LCD
8. Within 18 months from the date of manufacture, if the meter
still being sealed does not conform to any technical requirements
of IEC62053-21, the manufacturer guarantees to repair freely or to
change.
