**TECHNICAL DATASHEET** 

**Medical / Industrial AC-DC Power Supply** □J BNA 200 W Convection 2” x 4” / MEP-200A󠄒 

## **Functions** 

## Start-up Time 

The time required for output voltage to reach 90% of its final steady state value, after the input voltage is applied. 

## Rise Time 

The time required for 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. 

## 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 5 under “Protections”. Power supply will latch off, and require removal/re-application of input AC voltage in order to restart. 

## Overload & Over Current Protections 

The power supply’s Overload (OLP) and Over current (OCP) Protections will be activated before output current under 130 % of IO (max. load). Upon such occurrence, VO will start to drop. Once the power supply has reached its maximum power limit, the protection will be activated and the power supply will go into “Hiccup mode” (A󠄒uto-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 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. 

##  **50% to 100% Load** 

**Figure 6.  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. 

## Short Circuit Protection 

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. 

**Figure 5.  Dynamic Load** 

## Over Temperature Protection 

## 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. 

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 > 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.
