Functions
Start-up Time
The time required for the output voltage (Vo) to reach 90% of its set value, after the input AC voltage is applied.
Rise Time
The time required for the output voltage (Vo) to change from 10% to 90% of its steady state value.
Hold-up Time
Hold up time is the time when the AC input collapses and output voltage retains regulation for a certain period of time. The time
required for the output to reach 95% of its set value, after the input voltage is removed.
Graph illustrating the Start-up Time, Rise Time, and Hold-up Time
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.
Dynamic Response
The power supply output voltage will remain within ±3% of its
steady state value, when subjected to a dynamic load change
from 50 to 100% of its rated current.

Overload & Over current Protections
The power supply’s Overload (OLP) and Over current (OCP)
Protections will be activated when output current is between
110% and 250% of IO (Max load). Upon such an 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” (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.
Additionally, if the IO is <250% but >110% for a prolong period of
time (depending on the load), the Over Temperature Protection
(OTP) will be activated due to high temperature on critical
components. The power supply will then go into hiccup mode until
the fault is removed; and, the input voltage is removed, then
reapplied.
Short Circuit Protection (Auto-Recovery)
The power supply’s output OLP/OCP function also provides
protection against short circuits. When a short circuit is applied,
the output current will operate in “Hiccup mode”, as shown in the
illustration in the OLP/OCP section on this page. The power
supply will return to normal operation after the short circuit is
removed.
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 3 under “Protections”. Power
supply will latch off, and require removal/re-application of input
AC voltage in order to restart.
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 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
input voltage is removed; then, reapplied, and the surrounding air
temperature drops to its normal operating temperature.

Certificate
All Delta Medical Power products conform to the European directive 2011/65/EU. RoHS is the abbreviation for
“Restriction of the use of certain hazardous substances.
Typically, the input current waveform is not sinusoidal due to the periodical peak charging of the input capacitor.
In industrial environment, complying with EN 61000-3-2 is only necessary under special conditions. Complying
to this standard can have some technical drawbacks, such as lower efficiency as well as some commercial
aspects such as higher purchasing costs. Frequently, the user does not profit from fulfilling this standard,
therefore, it is important to know whether it is mandatory to meet this standard for a specific application.
In addition to a UL Total Certification Program (TCP) approved client laboratory for IEC60950 and IEC60065.
Delta also has participated UL Client Test Data Program (CDTP) for IEC 60601.
