Voltmeter ammeter + shunt 50A 100v + wire

The price is for a set of voltmeter module + 2 x leads + 50A shunt

• Voltage measurement 0-100V DC or 4-30 DC (depending on connection)
• Current measurement 0-50A (necessary to connect shunt from the set)
• Power supply 4-30V DC
• Error of voltage measurement ±0.1%
• Current measurement error ±1%
• Voltage and current measurement calibration possible
• Current drawn during operation < 20mA
• Refresh rate 300mS
• Display 0.28" LED
• Colour : V red A blue
• Dimensions display 2.9x4.8cm shunt 12x2.5cm

The module, like any digital circuit, requires a constant filtered DC voltage to work, otherwise the measurement "jumps" and is unreliable. It can be used in a rectifier, but it requires the "two halves" to be disconnected and filtered.
