Isolated Differential Voltage Sensor
The IsoBlock V-1c is a single-channel, galvanically isolated differential voltage sensor. Input voltage ranges span ±5V to ±1500V with selectable accuracy: standard ±(0.2% of reading + 0.005% of range) for industrial applications, or precision ±(0.1% of reading + 0.005% of range) for metrology work. The sensor outputs a differential ±10V signal (with ±5V and ±7VAC options) with 100kHz bandwidth (500kHz custom option available), measuring both DC and AC components simultaneously.
Measurement Capability
The V-1c measures differential voltage across two input terminals with complete galvanic isolation from your data acquisition system. Input voltage ranges span from ±5V to ±1500V. The sensor outputs a differential ±10V signal (with ±5V and ±7VAC options) that is galvanically isolated from the primary measurement circuit.
The V-1c simultaneously captures both DC and AC components with 100kHz bandwidth (500kHz custom option available). Common mode rejection at 60Hz reaches 112 dB.
Three-Way Galvanic Isolation
The V-1c provides primary-to-secondary and signal-to-power isolation rated for ±1500V sustained. Max common mode transient voltage is 5000V for 1 minute. Every isolation barrier is tested with 1800V partial discharge testing at 150pC detection threshold.
Non-Invasive Measurement with High Input Impedance
Input impedance scales with voltage range: 440kΩ (±5-30V), 2MΩ (±50-300V), and 8MΩ (±500V-1500V).
Electrical Performance
Excellent temperature stability (±50 ppm/°C gain drift, -25°C to +70°C operating range). Input-to-output linearity is <0.04% across the full measurement range, with phase shift less than 0.05° at 60Hz. Common mode rejection reaches 112 dB @ 60Hz. Max through delay is 3.8µs (100kHz bandwidth version). Output offset voltage is 2σ <±500µV typical (4σ <±1mV limit).
Compact DIN Rail Form Factor
Standard DIN rail mount (1.4" wide × 3.5" high × 2.5" deep, 198g) with spring cage connectors. Direct connection to standard twisted pair cable (20-6 AWG) and DAQ differential analog inputs. Low output impedance (20Ω).
