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.
