S03.1) TECHNICAL DATASHEET Medical / Industrial AC-DC Power Supply 1200W with 5V/2A Standby / MEB-1K2A series Functions Start-up Time Inrush Current The time required for the output voltage to reach 90% of its final steady state value, after the input voltage is applied. Inrush current is the input current that occurs when the input voltage is first applied. For AC input voltages, the maximum peak value of inrush current will occur during the first half cycle of the applied AC voltage. This peak value decreases exponentially during subsequent cycles of AC voltage. Rise Time The time required for the output voltage to change from 10% to 90% of its final steady state value. Hold-up Time Time between the collapse of the AC input voltage, and the output falling to 90% of its steady state value. Figure 6. Inrush Current Figure 4. Time Sequence Dynamic Response (Main Output) The power supply output voltage will remain within 5% of its steady state value, when subjected to a dynamic load 50 to 100% of its rated current. Overvoltage Protection The power supply's overvoltage circuit will be activated when its internal feedback circuit fails. The output voltage shall not exceed its specifications defined on Page 6 under "Protections". Power supply will latch off, and require removal/re-application of input AC voltage in order to restart. 50 to 100% Load Overload & Over current Protections Figure 5. Dynamic Load Main output Overload (OLP) and Over current (OCP) Protections is achieved by constant output current control. If the output current increases higher than rated current, the current will be clamped to be constant (<130% rated current), output voltage will then drop if output impedance keeps decreasing in the constant current control. Finally output under voltage protection will be triggered if the output voltage falls below 75% rated value and enters "Hiccup mode" (Auto-Recovery). The power supply will recover once the fault condition causing the OLP and OCP is removed and IO is back within the specified limit. Figure 7. Hiccup at OLP/OCP Additionally, if the Iout is >100% for a prolong period of time (depending on the load), the Over Temperature Protection (OTP) may be activated due to high temperature on critical components. The power supply will then go into latch mode. 10 All parameters are specified at 25C ambient unless otherwise noted. th www.DeltaPSU.com (Dec 6 , 2017, Rev. S03.1) TECHNICAL DATASHEET Medical / Industrial AC-DC Power Supply 1200W with 5V/2A Standby / MEB-1K2A series Short Circuit Protection Remote On_Off/Inhibit The power supply also provides protection against short circuits. When a short circuit is applied, the output current will operate in "Hiccup mode". The power supply will return to normal operation after the short circuit is removed. Remote ON_OFF/INHIBIT uses an isolated diode located within the power supply. This signal can be used to enable or disable only the main output. When the main output is disabled, the +5V Standby output will continue to operate. System can use a switch to conduct through this diode (suggested pull up resistor to 5V standby with 1Kohm resistor) to disable the main out. The signal can be floated (no connection to the signal), in order to enable the main output Over Temperature Protection As mentioned above, the power supply also has Over Temperature Protection (OTP). This is activated when the overload condition persists for an extended duration and the output current is below the overload trigger point but >100% load. In the event of a higher operating temperature condition at 100% load, the power supply will run into OTP when the surrounding air temperature is higher than the operating temperature. When activated, the output voltage will go into latch mode until the input voltage is removed; then, reapplied, and the surrounding air temperature drops to its normal operating temperature. System side 5V standby Power supply side Remote On_Off + Power Good Remote On_Off - Power Good+/- pin is an isolated open collector transistor (80V/50mA rating). A resistor (suggested value 10Kohm, 1/8W) can be added between Power Good- pin and DC RTN, Power Good+ pin can be connected to 5V standby (or, other available pull-up voltage that is no greater than the transistor rating). Value of resistor may have to be adjusted, depending on voltage used, and other end-use conditions of the Power Good+ pin connection to the product. When AC input is on, Power Good Signal (Shown in below figure) generated will be high. When AC input is off, Power Good Signal generated will be low. There will be a minimum of 5 milliseconds (at 1000W load) between the time the Power Good Signal goes to low level, and the time when the output reaches 90% of its rated value. Power supply side 5V standby System side Power Good + Switch Signal DC RTN Figure 10. Remote On_Off Connection Remote Sense Remote sense feature can be used to compensate for the extra voltage drop on output wires that are connected from the main output terminals, to the load. With wires connected from the remote sense pins, at the same locations as the wires from the main output, the remote sense function can compensate up to 500mV voltage drop. The power supply will not be damaged if the remote sense pins are shorted, or if a reverse/inverted polarity connection is made to the load. Voltage Adjustment Power Good Power Good Signal DC RTN Figure 8. Power Good Connection The power supply provides a potentiometer for user to adjust the output voltage. The output voltage is designed to be able to adjust up to 10% of rated voltage, when the output is adjusted below nominal value, the maximum output current is the same as the nominal output, when the output is adjusted above nominal value, the output power cannot exceed the nominal maximum power (the maximum output current will be reduced accordingly). PMBus The power supply can communicate with the host product, using PMBus version 1.3 protocols. Multiple functions can be realized, such as monitoring the power supply operation status, and editing the power supply operating set-points. See user instruction for detailed control information. Current Sharing The power supply supports current sharing. Parallel the outputs as well as the current sharing bus to enable this feature. Figure 9.
