The PROtop series power supplies are designed and engineered for challenging industrial environments. The series combines dynamic current limiting (DCL) technology for safe triggering of circuit breakers with efficiencies of as much as 95.4% for longer life spans. An integrated ORing MOSFET for redundancy or parallel operation without a diode, along with the optional communications interface for data monitoring and transfer to control systems, makes the power supplies Industry 4.0- and IIoT-ready. The DCL technology provides unique impulse energy reserves for optimal system availability. A peak current reserve of 600% for 20 ms provides safe and reliable circuit breaker triggering.
