150W Open Frame Power Supply for Medical Class

Large Image Download Center

Total Output Power:
150W at 50°C environment temperature (Note 4)
1) The maximum total combined output power on the +3.3V and +5V rails is 90W
2) Measured by a 20MHz bandwidth limited oscilloscope and the each output is connected with a 10uF Electrolytic Capacitor and a 0.1uF Ceramic Capacitor
3) Initial Setting Accuracy is at Input 110VDC and all output at 60% rated load
4) The total DC continuous power shall be kept with 150W at input voltage at 110-264VAC. With input voltage 90-109VAC the total DC continuous power shall be kept will 120W max. The maximum total combined output power on the +3.3V and +5V rails is 90W. On condition of with the option cover, the maximum 150W is at 30°C environment temperature (Please see part 6 of operating temperature)
Input Specification:
Power On/Off:
The power supply will be turned on when the power On/Off pin is connected to secondary GND
Power Good Signal:
When power is turned on, the power good signal will go high 100ms to 500ms after all output DC voltages are within regulation limits
Power Fail Signal:
The power fail signal will go low at least 1mS before any of the output voltages fall below the regulation limits
Short Circuit Protection:
The power supply will go into hiccup mode against short circuit or over load conditions, and will auto-recovery while faulty conditions are removed
Over Voltage Protection:
For some reason the power supply fails to control itself, the build-in over voltage protection circuit will shut down the outputs to prevent damaging external circuits. The trigger point is about 5.8-6.4V at +5V. If the OVP occur, PSU cannot be recovered
Over Temperature Protection:
When the power supply operting over the temperature or over load limit, the power supply will be shut down automatically to protect itself. The protection point is at the temperature of the HS1 over 110°C. After the temperature of HS1 going down, the power supply will restart automatically
Environment Specification:
19.8 x 9.7 x 4.05 cm, Tolerance +/-0.4mm
