**TECHNICAL DATASHEET**
**Medical / Industrial AC-DC Power Supply** 2,500 W with 5 V/2 A Standby / MEB-2K5A series
## **Functions**
## Start-up Time
The time required for the output voltage to reach 90% of its final steady state value, after the input voltage is applied.
## Rise Time
The time required for the output voltage to change from 10% to 90% of its final steady state value.
## 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.
## Overload & Over current Protections
## Hold-up Time
Time between the collapse of the AC input voltage, and the output falling to 90% of its steady state value.
**Figure 2. Time Sequence**
## Dynamic Response (Main Output)
The power supply’s Overload (OLP) and Overcurrent (OCP) Protections will be activated when output current exceeds 130% of IO (Max load). In such occurrence, the VO will start to drop and once the power supply has reached its maximum power limit, the protection is activated and the power supply will go into “Hiccup mode” (Auto-Recovery). The power supply will recover once the fault condition of the OLP and OCP is removed and IO is back within the specifications.
Please be noted the output current might be clamped in constant current mode and in this case, the protection will be triggered by output undervoltage point. (85% of rated output voltage for 24V; 80% of rated output voltage for 36V; and 82% of rated output voltage for 48V).
The power supply output voltage will remain within ±10% of its steady state value, when subjected to a dynamic load 50 to 100% of its rated current.
## ◼ **50% to 100% Load**
**Figure 5. Hiccup at OLP/OCP**
## Short Circuit Protection
**Figure 3. Dynamic Load**
## Inrush Current
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.
Output OLP/OCP function 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.
## 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 hiccup mode until the surrounding air temperature drops to its normal operating temperature.

**TECHNICAL DATASHEET**
**Medical / Industrial AC-DC Power Supply** 2,500 W with 5 V/2 A Standby / MEB-2K5A series
## Power Good
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 between the time the Power Good Signal goes to low level, and the time when the output reaches 90% of its rated value.

## Remote On_Off/Inhibit
Remote ON_OFF/INHIBIT uses an isolated diode (6V/50mA rating) 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 500 to 1Kohm resistor) to disable the main out. The signal can be floated (no connection to the signal), in order to enable the main output.

**Figure 8. Remote On_Off Connection**
## Remote Sense
**Figure 6. Power Good Connection**
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/Current Adjustment
**Figure 7. Power Good Time Sequence**
The power supply provides a potentiometer for user to adjust the output voltage in CV mode or to adjust the output current in CC mode. The output voltage is designed to be able to adjust above the normal rated voltage, 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.
All parameters are specified at 25°C ambient unless otherwise noted. **PSU.deltaww.com (September 2025, Rev. 01.1)**

## Current Sharing
The power supply has an active current sharing circuit for the main output; it can realize the output current to be balanced when customer is using up to four power supplies in parallel to achieve higher output power. A one wire current share bus is used to achieve current sharing between units, the current share bus must be connected together among different units (pin 13 of CN602, refer to power supply mechanical drawing and pin assignment). The difference in output voltage can impact the current sharing accuracy, all the units to be paralleled, please use the voltage adjustment function to set the voltage to be ±50 mV of the set value, and the maximum output current set at 80% of rated output current.
## CC/CV mode selection
Pin14 of CN602 can be used to select from constant voltage output mode or constant current output mode, if the pin is left open the output will be default as constant voltage output, if the pin is shorted to ground return, the output will be selected as constant current.
The paralleled units can be connected with or without remote sense function, Figure 9 &10 are typical connection of the parallel connections.
