Compact current converter COMBITRON 98

DCswitchingAC power supply

Description
With the COMBITRON 98, KEB offers a fast-acting rectifier with overexcitation for optimum activation and deactivation times of spring-applied brakes and electromagnets. Two Powerbox designs in rigid housing — DIN-rail mount or screw-on version — complete the range. Faster switching times and the potential for significant energy savings make the COMBITRON 98 a practical choice for braking and magnet control.

Highlights

• Two versions
• Up to 94% power reduction
• Overexcitation capability
• Up to 300 V
• UL-certified
• Compact plastic housing
• Low intrinsic heating
• DC-side and AC-side switching
