Introduction

The DHAB series is ideally suited for DC, AC, or pulsed current measurement in high-power, low-voltage automotive applications. It features galvanic isolation between the primary circuit (high power) and the secondary circuit (electronic circuit). The DHAB series allows users to select different current measurement ranges (from ±20 A to ±900 A) within the same housing.

Features

Open-loop sensor based on Hall effect
Low-voltage applications
Single +5 V DC supply
Channel 1 primary current measurement range up to ±75 A; Channel 2 up to ±500 A. Maximum RMS primary current: determined by busbar to keep temperature T < +150 °C
Operating temperature range: -40 °C < T < +125 °C
Ratiometric output voltage (sensitivity and offset)
Dual-channel sensor with wider measurement range and redundancy
Good accuracy across both high and low current ranges
Good linearity
Low thermal offset drift
Low thermal sensitivity drift
Sealed package
