4-1／2数字直流电压表，1 / 8 DIN DP3001 1年保修 CE DC Voltmeter, 1/8 DIN DP3001:4-1/2 Digit DC Voltmeter, 1/8 DIN DP3001-5 ±19,999 Count Display Span ±2 V to ±200 Vdc Ranges True-Differential Input 120 dB CMR, 56 dB NMR 1 pA Typical Bias Current 3-Wire Ratio Measurement Bright, 14 mm (0.56") LED Display Automatic Zero and Polarity Display Hold and Test 115/230 Vac Power Short 104 mm (4.1") Deep 1/8 DIN Case Options Isolated 9 to 32 Vdc Power Isolated 26 to 56 Vdc Power Screw-Terminal Barrier Strip NEMA 4 (IP65) Splash-Proof Lens Cover The DP3001 is a low-cost, true-differential 4-1/2 digit panel meter for applications that require high resolution and high accuracy DC measurement. It fits a standard 1/8 DIN panel cutout and requires a depth of less than 104 mm (4.1") behind the panel. Display span is ±19,999 counts. Accuracy is 99.98%. INPUT RANGES The DP3001 offers DC voltage ranges of ±1.9999, ±19.999 and ±199.99 Vdc. By using an external DC voltage reference, any of these ranges can be configured for 3-wire ratio measurement. OPTIONS The meter can be electrically configured for three input voltage ranges, four decimal-point positions, high-impedance 3-wire ratio input. Mechanical options include a screw-terminal barrier strip for signal and power and a splash-proof lens cover which meets NEMA 4 (IP65) requirements.
