Masked input power outages

Any input power outage lasting at max:

  • 1 ms at full load & minimum line voltage (i.e. 19.2 Vdc)

  • 10 ms at full load & nominal line voltage (i.e. 24 or 48Vdc)

Must not induce any change in the output characteristics. Period between interruptions 1 sec.

Input Protection

  • Protection against risk of fire: by a fuse mounted on the board, not accessible and not changeable by the user and located on DC+ input. Its rating is selected to comply with safety standards. It shall not be damaged during line noise withstand tests, under any circumstances.

  • Protection against reverse input polarity: a built-in circuitry must protect the module. The internal (and eventual external) fuse(s) must not blow up. The power supply must start-up correctly when the right polarity is restored.

Output characteristics:

Output Nominal Voltage

24.35 V

Output Steady-State Voltage Range

23.3...24.7 V over the entire input voltage range, over the full output load range, and over the full temperature range.

Output Ripple and Noise

240 mV peak to peak (measured with a bandwidth ≥100 MHz, on the module connector pins.

Continuous Output Current Range

  • 1.63 A maximum

  • 0 A minimum

Transient Output Current Capability

1.9 A maximum during 500 ms, period minimum 20 sec.

Output impedance versus frequency

180 mΩ

Output Voltage Response to transient load on 24V_BAC

For the following output load transient on 24V_BAC:

  • Load variation I from minimum continuous output current limit to max transient output current limit (and vice versa).

  • Transition time 4 μs – pulse width 500ms – period 20 sec.

  • The transient output voltage on 24V_BAC must stay within the limits 23.0...25.0V, and the response time must be ≤ 50 ms.

  • Whatever the value of the capacitive load on 24V_BAC in the specified limits.

Protection against output overload/short-circuit

  • In case of any condition of overload or short-circuit on 24V_BAC (i.e. any case of level, duration, temperature, input voltage), the board must be protected from any damage.

  • The overall maximum value of the overload detection threshold (i.e. including all tolerances, drifts, etc.) must be less than Imax.

  • Imax = 2 A.

Protection against overvoltage

Disjunction of the power supply for a rise of the output reaching 30.0 Vdc ±.8 V.

External Capacitive Load Capability

All the above characteristics must be fulfilled with the following external capacitive load value. This feature must be considered notably for slope-up, regulation loop stability and overload detection/protection.

11500 μF capacitive value.
