Corresponding to the UL safety standard UL61800-5-1 for industrial equipment, Asahi Kasei Microdevices, (AKM), has developed the CZ-3A0x series coreless current sensor, which achieves both creepage distance and clearance greater than 8mm. With a wide current detection lineup from ±12.9 to ±129.1App, 50Arms, and two overcurrent protection circuits, the CZ-3A0x series can be used for many applications including AC motors and general-purpose inverters. In addition, it is suitable for a sensor signal input to a 3.3V A/D converter.
By developing AKM’s original package, both creepage distance and clearance of 8mm or more is achieved. It supports a Working Voltage of 600Vrms (with reinforced insulation), making insulation design easy.
The CZ-3A0x series has a low resistance of 0.27mΩ as the primary conductor resistance with AKM’s original package. As a result, compared to shunt resistors and similar products of other companies, heat generation when applying the current can be greatly suppressed, and 50Arms continuous current is achieved. Furthermore, availability with wide current detection ranges from ± 12.9App, (CZ-3A01), to ± 129.1App (CZ-3A07) is available. This enables adoption of a common design of system boards, making it easy to roll it out to other models with different ratings.
The CZ-3A0x series supports 3.3V output. It is best for a sensor signal input to a 3.3V A/D converter.
The CZ-3A0x series is suitable for overcurrent detection since it has two overcurrent detection circuits.
