2938963 Phoenix Contact QUINT-DIODE40 Power redundancy module Diode module

The Phoenix Contact 2938963 (officially designated QUINT-DC/DC/24DC/20) is a premium 24 V DC to 24 V DC isolated DC/DC converter engineered for critical industrial power applications requiring galvanic isolation, voltage stabilization, and seamless redundancy. As part of the renowned QUINT POWER family, this 20-amp module delivers 480 W of reliable, regulated output power with advanced features like Active Current Limiting, Power Boost, and integrated diagnostics—making it indispensable in automation, energy, transportation, and process control systems where power integrity is non-negotiable.

Unlike standard DC/DC converters, the 2938963 provides true galvanic isolation (up to 5 kV AC) between input and output, effectively breaking ground loops, suppressing noise, and protecting sensitive downstream electronics from transients or faults on the primary DC bus. Its robust design supports operation in harsh electrical environments, including those with fluctuating battery voltages, high ripple, or long cable runs.
