General Description
TRACO’s TEN-25WI-Series power modules are low-profile dc-dc converters that operate over input voltage ranges of 10-40VDC and 18-75VDC
which provide precisely regulated output voltages of 3.3V, 5V, 12V, 15V, ±12V and ±15VDC, specially addressing data communication equipments,
mobile battery driven equipments, distributed power systems, telecommunication equipments, mixed analog/digital subsystems, process/machine
control equipments, computer peripheral systems and industrial robot systems.
Packing up to 30W of power into a 2x1.6x0.37inch package, with efficiencies as high as 89%, the TEN 25WI includes continuous short circuit
protection, overvoltage protection, over temperature protection, output trim function, remote on/off, six-sided shielded case and EN55022 Class A
conducted noise compliance minimize design-in time, cost and eliminate the need for external filtering.

This noise pickup is eliminated as shown in Figure by using a scope probe with an external ground band or ring and pressing this
band directly against the output common terminal of the power converter while the tip contacts the voltage output terminal. This
makes the shortest possible connection across the output terminals.

Input Source Impedance
The power module should be connected to a low ac-impedance input source. Highly inductive source impedances
can affect the stability of the power module.
In applications where power is supplied over long lines and output loading is high, it may be necessary to use a
capacitor at the input to ensure startup. Capacitor mounted close to the power module helps ensure stability of the
unit, it is recommended to use a good quality low Equivalent Series Resistance (ESR < 1.0Ω at 100 KHz) capacitor
of a 33µF for the 24V input devices and a 10µF for the 48V devices.
Output Over Current Protection
To provide protection in a fault (output overload) condition, the unit is equipped with internal current limiting circuitry
and can endure current limiting for an unlimited duration. At the point of current-limit inception, the unit shifts from
voltage control to current control. The unit operates normally once the output current is brought back into its specified
range.
Output Over Voltage Protection
The output overvoltage clamp consists of control circuitry, which is independent of the primary regulation loop, that
monitors the voltage on the output terminals. The control loop of the clamp has a higher voltage set point than the
primary loop. This provides a redundant voltage control that reduces the risk of output overvoltage.
The OVP level can be found in the output data

Safety and Installation Instruction
Fusing Consideration
Caution: This power module is not internally fused. An input line fuse must always be used.
This encapsulated power module can be used in a wide variety of applications, ranging from simple stand-alone
operation to an integrated part of sophisticated power architecture. To maximum flexibility, internal fusing is not
included; however, to achieve maximum safety and system protection, always use an input line fuse.
The safety agencies require a slow-blow fuse in 24Vin, 48Vin with maximum rating of 5000mA, 3000mA. Based on
the information provided in this data sheet on Inrush energy and maximum dc input current; the same type of fuse
with lower rating can be used. Refer to the fuse manufacturer’s data for further information.
