General Description
3
Delta’s new MDS-400APB12 open frame design offers a high energy density (19 Watts/in ) 3x5 inch design for Type BF patient access
medical products. With operating parameters of 90 to 264 Vac universal input voltage, temperatures of -10 to +70 degrees centigrade,
and altitudes of up to 5000 meters (16,400 feet), the design is well suited for a variety of both medical and non-medical applications.
Other features include input surge of 300 Vac, low leakage current, no-load input power < 0.5 Watt, and 500K hour MTBF. This
product is certified for EMC standards EN 55011 for industrial, scientific and medical (ISM) radio-frequency equipment, and EN 55022
for Industrial Technology Equipment (ITE) radio-frequency equipment. In addition, only recognized Japanese capacitors are used to
ensure long product life.
An enhanced feature set, includes a 5 Volt/2 amp standby output, remote on/off, remote sense, and a power good signal that are
included as part of the standard product.
The design, which has protection against shock compliant with 2XMOPP and Type BF requirements, has both medical (with risk report
available), and ITE safety approvals, including cURus (US&Canada) /TUV/GB(China); plus, CB certificates with all national deviations.
Full compliance with RoHS Directive 2011/65/EU for environmental protection is included. The unit comes in a standard 3x5 inch
footprint, with height suitable for 1U applications. Robust terminals are capable of multiple connections of the main output to the end
product.

Functions
Start-up Time
The time required for the output voltage to reach 90% of its set value, after the input voltage is applied.
Rise Time
The time required for the output voltage to change from 10% to 90% of its set 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 90% of its set value, after the input voltage is removed.

Dynamic Response
Short Circuit Protection
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
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.
Inrush Current
Inrush current is the peak, instantaneous, input current measured
and, 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.
Overload & Overcurrent Protections
The power supply’s Overload (OLP) and Overcurrent (OCP)
Protections will be activated before output current under 160% of
I O (Max load). Upon such occurrence, V O 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 I O is back within the specified limit.
Additionally, if the Iout is <160% but >100% 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
latchmode.
Over Temperature Protection
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 4 under “Protections”. Power
supply will latch off, and require removal/re-application of input
AC voltage in order to restart.
10
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.
All parameters are specified at 25°C ambient unless otherwise noted.

12V/400W 3”x5” High Density MDS-400APB12 AA
Power Good
Power Good+ pin is an open collector transistor (40V/600mA
rating). A resistor (suggested value 10Kohm, 1/8W) can be added
between 5V STANDBY pin (or, other available pull-up voltage
that is no greater than 30V) and the Power Good+ pin (refer to
figure below). Value of pull-up 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+ pin will be high. When AC input is off, Power
Good+ pin will be low. There will be a minimum of 3 milliseconds
between the time the power good goes to low level, and the time
when the output reaches 90% of its rated value.
11
Remote On_Off/Inhibit
Remote ON_OFF/INHIBIT 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. This signal can be pulled
down to a low level of 0.3 volts, or shorted to DC-Return, in order
for the main output to be enabled; and, floated (no connection to
the signal), or pulled up to a value greater than or equal to 3 volts,
in order to disable the main output.
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.
All parameters are specified at 25°C ambient unless otherwise noted.
