We are the only people in the UK that can supply the FRIWO power supply range and have been since 1986. 

We have the full support and manufacturing capabilities behind us.

The FRIWO Range is built to the highest standards using tier 1 components, we have always been on the forefront of technology 

We also have our on large UK facility for stock storage and production

We have been doing this for a very long time, in fact we used to make plugin linear power supplies in our town office!

The simple answer is, Growth.

With the increase demand and move to switch-mode technology we just couldn’t keep up by means of individual component placing, manual core winding and a singular injection molding machines.

We now have support of over 1,800 production staff worldwide and machine automation, to make sure we keep up with demand and to guarantee things run efficiently!

Of Course!

We have 2 meeting rooms on site where we can discuss power projects.

While you're there we can give you a tour of our facility, demo some new tech and maybe challenge you to a game of Ping Pong!

The current which, during operation of a device, flows out via the capacitances and the insulation resistance of the operating circuit via the protective conductor of the device to earth.

Temperature range in which a device may be stored (not operated) without suffering damage.

The temperature range which must not be exceeded or fallen below when the device is in operation.

Short circuit proof means that a temporary short circuit can be tolerated without damage.

Continuous short circuit proof means that a short circuit can be present for a long time without damaging the output. Once the fault has been rectified, the output operates normally again.

EMC stands for the ability of an electrical device to function satisfactorily in its electromagnetic environment without unacceptably influencing its environment, which also includes other devices. Power supply units should comply with at least two basic EMC standards:

1. the standard for emitted interference (interference that the power supply unit emits or radiates in a conducted fashion) and

2. the standard for immunity (protection against external interference). These generic standards comprise a large number of other sub-standards, each of which defines limit values for sub-sectors (e.g. certain types of interference). FRIWO power supplies usually comply with these standards to a stricter degree than required because we believe that the EMC of our devices should be as good as possible in order to enable trouble-free operation.

MTBF stands for Mean Time Between Failures. 

The MTBF indicates the statistical average time when a device fails due to processing or component faults before signs of wear and tear begin.

A temperature-dependent resistor with a negative coefficient, whereby the resistance value is greatly reduced with increasing temperature. 

Consequently, it is also called a thermistor. In addition to temperature measurement, it is also used to limit the inrush current of power supplies.

SMT (surface-mounted technology) is a surface mounting technology in which surface-mountable components (components without wire connections) are soldered directly onto a printed circuit board using solderable connection surfaces.

A control loop in the power supply unit keeps the output voltage constant regardless of all factors (e.g. temperature).

Current consumption of a power supply in no-load operation.

Electronic overload protection that limits the maximum output current to a preset value.

THT stands for the English term: through-hole technology and describes the through-hole assembly. In this type of assembly, the components have wire connections (“wired components”) and are inserted through the printed circuit board by means of contact holes and then connected by special THT soldering processes.

Temperature of the still air surrounding the unit. Is usually measured approx. 10 mm next to the unit in operation.

A power supply circuit monitors the output voltage. If a certain preset limit is exceeded, the power supply is deactivated.

The efficiency is calculated from the ratio of output to input power and is always less than one.

Single range

Power supply with an input voltage for operation in the particular countries.

Wide Range

Power supplies with wide-range input can be operated at different nominal voltages without the need to adjust them by (manual or automatic) switching.
