DIY Supplies : ELECTRICAL
Origin : Mainland China
Certification : none
Features:
1.One meter for dual use, controlling voltage and current simultaneously
2.Split type: Easy to install, with the transformer separated from the instrument. The transformer can be installed according to the actual measurement position (the lead wire at the secondary end of the transformer can be extended to achieve the ideal installation position)
3.Two wire system: There is no need to connect another power supply, and the two yellow wires on the 3P terminal are connected to measure the voltage while supplying power to the meter head (without the need for polarity separation)
4.There is no need to purchase an additional transformer for current testing, and the instrument comes with a high-precision transformer
5.The meter head is equipped with a built-in fine-tuning potentiometer, which can self calibrate voltage and current errors
Parameters:
Power supply voltage range: AC70-480V
Current measurement range: 10A (0.00-9.99A) -100A (0.0-100A) optional
Display method: LED digital tube display
Display color: (Full Red) Single color (Full Blue) Dual color (Red Blue)
Installation opening: 45.5 * 26.5mm
Measurement rate:>200mS/time
Special note: The display method can be color matched according to customer requirements
Measurement accuracy: 1% (± 1 word)
Terminal wire length: 20cm
Transformer wire length: 17cm
Attention:
1. The wiring sequence of the instrument is: first connect the 220V voltage of the current circuit, and then connect it. After connecting the 220V power supply, do not touch any components or circuits behind the instrument to prevent electric shock hazards.
2. Split type: Terminal 2P of 2.54 is connected to the AC transformer CT, and the two yellow wires are connected to measure the AC voltage. Do not connect them incorrectly, which will cause damage to the instrument. The responsibility is borne by oneself.
3. This table is designed using the principle of capacitor voltage reduction. As the impedance of the capacitor decreases with increasing frequency, it is not suitable for use in high-frequency electronic speed regulation, non mains sine wave frequency, or other occasions with high-frequency components, otherwise it may be easily burned!!!
4. When selecting a measuring range, it is not recommended that the larger the range, the better. The larger the range, the greater the error. It is recommended to be 1.5 or 2 times the actual test value
