Drok YB27VA-50A Digital Dual-Display Voltmeter, Black

• Small and lightweight; Dual display of voltage and current on the same screen at the same time.
• Voltage figures update automatically; High anti-interference capacity.
• Does not burn out if power is inversely connected; Rapid refresh rate.
• The test terminal shares the same earth wire with the power supply.
• Volt and amp potentiometers for precision adjustment.

Features: Display: 3 x 0.28-inch LED digital tubes; Display colour: Red/blue (2-colour display); Dimensions: 48 x 29 x 21 mm; Mounting cutout: 45.5 x 26.5 mm; Refresh rate: Approximately 500 ms/time; Operating temperature: -10 °C to 65 °C; Operating humidity: 10 to 80% (non-condensing); Working pressure: 80 to 106 kPa; Wiring: Black wire (thin): Vacant or buck circuit (module) negative; Red wire (thin): Power supply +; Black wire (thick): COM, common measuring; Red wire (thick): PW +, measures terminal voltage input positive; Yellow wire (thick): IN +, current input + (Please refer to the wiring diagrams for more details); Note: The voltage between the thin black and thin red wires must be between DC 4.5-30 V. The ammeter can only be connected to the negative terminal of the device under test. Over 5 A, for long-term, full-load continuous work, it is recommended that the measurement part of the wires is soldered directly to the socket. When the thin black wire is vacant, it is better to use insulating tape around the exposed part of the wire to prevent short-circuits. If the device is only to be used as a voltmeter, it is recommended that the yellow and black wires are connected together in order to avoid digital flashing of the ammeter; Package includes: 1 x digital voltmeter/ammeter, 1 x 50 A/75 mV current shunt.
