CurrentSensForVarFreqDrives

H904 Hawkeye Current Sensor Self-Calibrating, Temperature Compensated with 1M ohm Internal Resistance, Drives 0.91 Power Factor at Full Load, Typically Has a Minimal Pickup of 5% of the Magnetizing Current; Output is Used to Drive and Measure Voltage, or Sense Current (Selectable), Designed for Use with 50/60 Hz Variable Frequency Drives

The H904 is designed to provide the most accurate current sensing possible for single-phase AC drives on a 120Vac system. The H904 has an extremely wide measurement range, and can be configured to report current using any one of three different scaling factors. This makes it perfectly suited for varied loads and conditions.

The H904 Hawkeye is a compact single phase self-calibrating current sensor switch with adjustable voltage and current ranges. This device is designed for general purpose motor control applications where high accuracy and high voltage/current is required. Veris Industries is now marketing the H904 to provide simple protection for mixed load direct drive fans.

The H904 is a high-accuracy, self-calibrating Current Sensor Switch with configurable functions. With the model-based calibration method applied, the H904 can be used for the precision position control of brushless DC motor without any complicated setup procedure. This sensor switch has been tested during PWM operation. Features: Pre-defined current range: 10~700A; Provides 4 configuration options.

Veris Industries, Inc. Introduces the H904 "Hawkeye" self-calibrating current sensor switch that provides fast and accurate switching for DC to AC inverters. The H904 is used with two-phase high frequency inverters in load sharing applications.

The H904 Hawkeye™ combines the functions of AC current sensing and phase angle measurement on three wires into a single compact unit. As simple as connecting the wires and pressing a button to autocalibrate, the Hawkeye ™ provides a direct digital readout of three-phase current with user-defined accuracies of ±0.5% or ±1% RMS. The Hawkeye ™ has built-in zero, span and short-circuit detection to simplify installation and

The H-904 is a self-calibrating, digital current sensor designed for use in PV inverters. Conventional current sensing devices are based on the Hall Effect, but the H-904 makes use of the magnetic induction effect. This patented self-calibration technique results in a higher accuracy, more linear response, and a wider sensor temperature range than with conventional current sensors.
