Corresponding to the UL safety standard UL61800-5-1 for industrial equipment, Asahi Kasei Microdevices Corporation, (AKM), has developed the CZ-370x series coreless current sensor, which achieving both creepage distance and clearance distance greater than 8 mm. With a wide current detection lineup from ±5.3 to ±180 App, 60 Arms, the CZ-370x series can be used for many applications including AC motors and general inverters.
By developing AKM’s original package, both creepage distance and clearance distance of 8 mm or more are achieved. It supports a Working Voltage of 600 Vrms (with reinforced insulation), making insulation design easy.
The CZ-370x series has a low resistance of 0.27 mΩ 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 60 Arms continuous current can be applied. Furthermore, availability with wide current detection ranges from ± 5.3 App (CZ-3700) to ± 180 App (CZ-3706) is achieved. This enables to adopt a common design of system boards, making it easy to roll it out to other models with different ratings.
The CZ-370x series is ultra-high accurate coreless current sensor with 0.5% F.S. (typical). In addition, it has a built-in stray magnetic field reduction function, a challenge for conventional coreless current sensors, contributing to improvement of system efficiency and precise control in a wide range of applications.
