Home - Products - Single/Three Phase Electronic Prepayment Wattmeter
Product Name: Single Phase Electronic Prepayment Active Wattmeter (Key-Card type)
Product Model: DDSY1000
Introduction:

Functions and features

1. All-digital chip makes single-phase active energy metering achieved. Prepayment ensures the use of electricity.

2. power-off alarm will call users’ attention to recharge promptly when the electricity is low.

3. When the load exceeds the power limit, auto power-off will occur to avoid overload of electricity.

4. IC card automatically read the data of the meter during the recharge, by which the data will be read into managing system. It is convenient for check.

5. Two directions power can be metered. Power-stealing will be effectively prevented.

6. Breaker using magnetic latching relay, high overload capacity, high reliability, long life.

7. Anti-attack module is installed to electric card socket to prevent vandalism and attacks. Strong anti-interference ability. The most adverse conditions: DC 2500V; AC 600V; static 30000V.
