The built-in OR-ing FET allows the power supply to operate in active current sharing mode for redundant (N+1) operation. Additional features include I2C interface, builtin fan and a 5V standby auxiliary output. The CEF400-112 provides reliable 12V bulk power for Information Technology Equipment and Industrial Applications. 40/60 50-96W load (2 in parallel) 20/80 Temperature Coefficient 1 % 20 500 1500 ms Vrms 0.02 % / °C Ripple and noise are measured with 0.1 μF of ceramic capacitance and 10 μF of tantalum capacitance on each of the power supply outputs. The output noise requirements apply over a 0 Hz to 20 MHz bandwidth. A short coaxial cable with 50Ω scope termination is used.

Power supply will provide a minimum of 5ms from loss of AC input before this signal goes high. Additionally a minimum of 3ms of holdup will be provided between the signal going high and the output going out of regulation. The signal will not go high when loss of AC input is less than 5ms in duration. AC Fail DC OK TTL logic goes high after the output is in regulation. It goes low when there is loss of regulation. Remote On/Off TTL logic input signal disables the output when held low, and enables the output when held high. Remote Sense Compensates for 0.5 V lead drop min. Will operate without remote sense connected. Unit is protected against reverse connection of the remote sense lines.
