Regulated power supply
Miki Pulley electromagnetic brakes are primarily of the non-excited type and use rectified power supplies. Rectification methods include full-wave and half-wave rectification, and input voltages
range from 100 V AC to 400 V AC, and connection options include terminal block and lead wire types, among others. These products also feature various functions designed to suppress heat generation and reduce power consumption in non-excited
brakes.

| Specifications | This is the basic model of a power supply unit designed to control electromagnetic clutches and brakes with a rated voltage of 45/90/180 V DC. | This is a compact power supply unit for non-excitation-type brakes rated at 45/90/180 V DC, featuring a terminal block design for easy connection. | This power supply can accommodate both half-wave and full-wave rectification outputs by changing the connection configuration. It supports a wide range of specifications. | After full-wave rectification, the system switches to half-wave rectification. This allows for both over-excitation and under-excitation effects. | The main unit is molded from resin, making this a lead-wire type suitable for use even in harsh environments. | This lead-wire type connector is ultra-compact and features a resin-molded body, making it suitable for use even in harsh environments. |
