Description
ISO1000-10 is a high precision high bandwidth voltage transducer that is capable of measuring AC and DC voltages up to ± 1000V with ± 0.1% accuracy. The device is rated 4.2KV rms galvanic isolation with advanced voltage sensing, common mode decoupling, and isolation technology built-in to ensure safe and accurate high voltage measurement. Excellent dynamic characteristics provide large signal bandwidth of 50 KHz and high common mode rejection of 110 dB @ 60Hz. The ISO1000-10 is ideal for high voltage sensing that requires high accuracy, fast response, high common mode rejection, wide operating temperatures (- 40 °C to 85 °C ), and a small footprint. The ISO1000-10 is easy to use and does not require additional components. The device has an internal integrated isolation power supply and circuitry for direct high voltage sensing. Just apply nominal ± 12Vdc power and high voltage to be sensed, the device will output a galvanic isolated voltage signal with voltage attenuation gain of 100. High voltage input pins are “+” and “-” with maximum differential voltage of ± 1000V and voltage rated 4.2KV rms with respect to ground. Operating power supply requirement is ± 12Vdc nominal (range: ± 11V to ± 16V). Pin “VCC” is +12V input, Pin “VEE” is -12V input, and pin “GND” is ± 12V return or GND. Pin “VOP” (reference to Pin “VON”) is the output with full scale output voltage of ± 10V. Pins “+”, “-” and Pins “VCC”, “VEE”, “GND”, “VOP”, “VON” are isolated with reinforced insulation of 4.2KVrms isolation rating. Output to input voltage gain is 1:100. The ISO1000-10 has excellent gain linearity with typical ± 0.0002% nonlinearity (±100V to ±1000V) and maximum ± 0.0005% nonlinearity at low voltage range (< ±100V). Gain deviation as a function of temperature is typically ± 0.0055% /°C. Output voltage offset drift is typically ±42µV /°C. High voltage input resistance is typical 1.5 MΩ and it requires very small power from high voltage bus circuit being sensed. For example, power drawn from a 1000Vdc high voltage bus is 0.67 watts. The input resistance is optimized with dynamic characteristics, DC characteristics, and thermal performance of the device. The ISO1000-10 requires small quiescent current (41 mA @ +12V) from its VCC input power supply and 2.7 mA max from VEE. The internal integrated isolation power supply is derived from the VCC input to power up high voltage side circuitry. |
