Delta’s new MDS-300APB48 open frame design offers a high energy density (14.3 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 800K 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/0.5 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.

Dynamic Response (48 Volt Output)
Overload & Over current Protections
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 Overload (OLP) and Over current (OCP)
Protections will be activated before the 48 volt outputs’ current
exceeds 160% 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. For the standby
output, the performance is the same, with the exception that the
protection will be activated before the output current exceeds
1.06 amps.
Inrush Current
Inrush current is 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.
Additionally, if the 48 Volts’ Iout is >100%; but <160% for a
prolonged 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 latch mode.
Short Circuit Protection
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.
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 5 under “Protections”. Power
supply will latch off, and require removal/re-application of input
AC voltage in order to restart.
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
.

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 5 milliseconds
(at 240W load) between the time the power good goes to low
level, and the time when the output reaches 90% of its rated
value.
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
