Description
Product introduction:
DC ammeter 45C3-A is installed on the power equipment of ships or other occasions. It measures AC voltage with a rated working frequency of 50Hz and 60Hz, and a wide-angle power meter with AC current.
The DC ammeter and the AC ammeter are very different. They cannot exchange measurements, and there is no way to exchange measurements. For high-current ammeters, the DC ammeter is actually just a 75 millivolt DC voltmeter (the millimeter on the shunt is measured). Voltage), and the internal resistance of the AC ammeter is very small (measured is the short-circuit current of the transformer secondary), which is short-circuited to the circuit, and the current can allow AC 5 amps to flow.
Accuracy: ≤ ± 0.1% RO
Display: DC current, DC voltage,
Output: relay alarm output, communication RS485, analog signal 4-20mA, 0-10Vdc, 0-5Vdc, etc.
Power supply: AC220V, DC12V, DC24V, DC48V or other special specifications
1. Purpose:
Embedded installation on ships, locomotives, power stations, mining metallurgy, petrochemicals or other mobile electrical equipment and devices to measure DC current or voltage. It can also be used as a secondary meter for converting non-electricity to electric energy.
2. Main technical performance:
Class 2.5, splash proof and vibration resistant.
3. Conditions of use:
Ambient temperature: -25 ～ + 55 ℃, relative temperature: <98% RH
4, measuring range:
