WATTMETER 100 AMP CAPACITY FITTED WITH DEANS CONNECTORS Specifications:Working Temperature RangeÔºö -20 ‚ÑÉ to 50 ‚ÑÉ WeightÔºöabout 57 grams DimensionÔºö 38x 49x 17mm Working voltage range:8-30V Working current range :0-100AÔºàtwo T-plugs requiredÔºâ Product ApplicationÔºö It‚Äôs designed to measure the power of electronics. Advertising High LightÔºö 1. Ultra portable. And light 2. calibration of current's standard 3. Data comparing mode. 4. Manual calibration function built-in 5. Using special current sensor. High precision, low resistance. The ordinary wattmeter uses the constantan wire as the resistance. These wattmeters'Ôºàused the constantan wire) nominal resistance is:0.001 Ohms(Œ©) P1's nominal resistance is:100 µŒ© =0.0001 Ohms(Œ©) (10% of 0.001 Ohms) Low resistance brings low power loss. The advantage of electromagnetic induction electric current sensor :not the normal resistance shunt sampling,nearly no essential resistance,so nonloss.precision is much higher than constantan wire
