CZ370x Current Sensors

Corresponding to the UL safety standard UL61800-5-1 for industrial equipment, AKM has developed the CZ370x series coreless current sensor which achieves both creepage distance and clearance distance greater than 8 mm. With a wide current-detection lineup from ±5.3 A to ±180 A, 60 ARMS, the CZ370x series can be used for many applications including AC motors and general inverters. It also supports a working voltage of 600 VRMS with reinforced insulation, making insulation design easy.

The CZ370x series has a low resistance of 0.27 mΩ. 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 A (CZ3700) to ±180 A (CZ3706) is achieved. This allows the user to adopt a common design of system boards, making it easy to roll out to other models with different ratings. In addition, it has a built-in stray magnetic field reduction function - a challenge for conventional coreless current sensors - contributing to the improvement of system efficiency and precise control in a wide range of applications.
