The MBC401 Series of AC-DC power supplies provides up to 400
W of regulated output power through wide input voltage range 90
–
264 VAC in single outputs of 12, 24, 28, 36 or 48 VDC.
The MBC401 Series comes in five different low-profile packages,
offering 12 and 5 VSB standby outputs and a full set of protection
features. Available control signals include Power Good (P_OK),
Remote On/Off (PS_ON) and remote sense compensation on the (+)
load line.
The MBC401 Series complies with the latest international safety
standards for medical equipment, offers 2xMoPP means of patient
protection, is suitable for BF rated applied parts and displays the
CE-Mark for the European Low Voltage Directive (LVD).

* The combined output power of V1, V2 and 5 V
SB
for -T and -S models, must not exceed 400 W up to 50 °C, and 280 W at 70 °C
ambient temperature. See de-rating curves below.
** The combined output power of V1, V2 and 5V
SB
for (-), -UC, -PC models, must not exceed 400 W when cooled by 400 LFM air
flow, and 250 W when natural convection cooled, up to 50 °C. Above 50 °C output de-rating applies. See de-rating curves below.
In any case, the heat sink maximum temperature should not exceed +110 °C at 50 °C ambient temperature.
*** When the load on the main output is less than 100 mA, V2 output voltage might regulate below its minimum value.
