Product Overview
Description
WDJB-702 three Phase Secondary Current Injection Universal Protection Relay Test Set 0.2 degree
A circuit of special adjustable DC power supply output is allocated on the rear panel, which has 110V and 220V two shifts that canbe used as test standby power supply on the spot. Rated current of this power supply is 1.5A, which can be used as DC power supply
of protective tester or switch loop supply. If overload or short circuit occurs, corresponding protector tube will be burned out （
2A／250V）, you will only need to change this protector tube at that time.
Products Description
1. Standard 4-phase voltage 3-phase current output
2. Single machine easy to operate
3. Dual operation mode, connected to the computer to run
4. Powerful software
5. Many switch contacts
6. Large LCD display
7. Self-protection function
8. With independent dedicated DC power output
9. High cost performance :It is a cross-professional joint design product that integrates advanced scientific and technological achievements from multiple disciplines. It combines the performance of a large-scale tester and the price of a small-scale tester, and has a high performance-to-price ratio.
