AKM’s coreless current sensors are high-accuracy and achieve both creepage and clearance distance Corresponding to the UL safety standard UL61800-5-1 for industrial equipment, AKM has developed the CZ-3A0x series coreless current sensor which achieves both creepage distance and clearance distance greater than 8 mm. It supports a working voltage of 600 VRMS (with reinforced insulation), making insulation design easy. With a wide current …
This is a DC-DC step-up converter based on LM2585-ADJ regulator manufactured by Texas Instruments. This IC was chosen for its simplicity of use, requiring minimal external components and for its ability to control the output voltage by defining the feedback resistors (R1,R2). NPN switching/power transistor is integrated inside the regulator and is able to withstand 3A maximum …

Toshiba Electronic Devices & Storage Corporation has introduced the TLP170AM and TLP170GM two new photorelays that can be used in security systems, which are used in building automation and other industrial equipment. The TLP170AM has a rated OFF-state output terminal voltage of 60V and constant ON-state current (ION) of 0.7A with the pulse operation of up to 2.1A. The TLP170GM is a 350V version with …
I was testing a couple of low-cost laser diodes that come from china and I was wondering why those diodes don’t have any protection/driver circuitry. Those diodes come with a simple series resistor for current control which is not a good idea nor stable. Laser diodes are harmful and should have some sort of constant …
