View the Electronic Accessory Range. As a manufacturer of electromagnetic components Industrial Drive Systems offers a comprehensive range of rectifiers for the operation of brakes and solenoids. Reliability, electromagnetic compatibility, safety and reduced fuel consumption are becoming more relevant than ever and are no less important than requirements such as reduced installation space, integration capacity and cost optimization.

Modern rectifiers do not only provide direct current but also optimize the operation of electromagnetic actuators especially in terms of dynamics, fuel consumption and life cycle for the respective uses. The fast development of industrial automation requires ever more intelligent products customized to the actuator systems. Our experience – especially with the integration of electronic assemblies on a variety of electromechanical actuators – meets these increasing demands. We are happy to assist you with solving your specific tasks and requirements.

electronicsPWM control to adjust the amount of power supplied to the load. Depending on the design of the electromagnetic device, the following effects can be achieved:

• shorter switching times when operating voltage is applied:

• stronger attractive force

• increased stroke or

• reduced power consumption

• lower thermal stress

• longer lifecycle

• shorter switching times when operating voltage is removed compared to standard conditions

Technical specifications:

Input voltage range:  18 - 40 VDC
Overexcitation voltage:  input voltage or max. 30 VDC
Holding voltage:  10% – 90% of rated voltage
Output current:  up to 2.5 A
Ambient temperature range:  -20 to +85 °C
Overexcitation time:  200 / 500 ms (other times upon request)
Voltage control:  with pulse-width modulation (PWM)
Basic frequency:  500 Hz (other frequencies upon request)

These modules are very compact and conveniently priced thanks to the consistent use of state-of-the-art microelectronics and power electronics components.
