Automotive Relay Tester 12V Auto Relay Diagnostic Tool Battery Checker Small Relay Tester with Clips

Easy To Use - The tester will automatically detect the pin position, the release time of the action, and the consistency of the relay in each test phase. If the tester lights up the green LED light, the relay is normal.
if the red LED light is on, the relay is abnormal..
To Operate - First, clip the alligator clip of the tester to the car battery, the black clip on the negative pole, and the red clip on the positive pole. When the red LED light is on, it means the tester can start the test. Check the relay before testing. Select the appropriate socket according to the pins, insert the relay into sockets, press the "Test" button, and the tester will automatically detect the pin position of the unknown relay..
Fitment - Suitable for most general-purpose automotive relays on the market. When testing, it needs to be connected to the car's 11V-15V battery. The car battery must be a 12V battery, and the battery voltage must be between 11V-15V.
2. The applicable coil resistance is preferably above 20 ohms..
Compact - Our automotive Relay tester is small and easy to carry around for on-the-go jobs or for easy storage. Its compact design allows easy use no matter where you are..
Simple and Quick - With our patented design this relay tester will give you the ....

3-Phase Voltage Monitoring Relay AC 220-440V Phase Sequence Protection Small Size Protection for Industry Applications

Dynamic phase loss, static phase loss protection: refers to the phase failure of any phase when the protected device is in the running state or non-operating state. The indicator light is in the form of red light and priority.
Wrong phase protection: A protection measure to prevent the phase sequence of L1, L2, L3 three-phase AC power supply from being connected incorrectly. Instant action. The indicator light is in the form of yellow light..
Voltage Unbalance Protection: Refers to a voltage imbalance that will affect the safe operation of the device. When the voltage imbalance rate is higher than 8%. The form of the indicator light is: the lack of phase red light is on, and priority..
Delay protection: When there is a fault, the monitor will delay after 1~2 seconds, and the relay will release..
The protection function of the monitor is not affected by the current of the line or load, the inrush current, the unbalanced current and the nature of the load. Long-term work with full performance and full climate. Power consumption is no more than 2W..
