Outdoor power supply is heavy and bulky

What is a heavy power supply?

A "heavy" power supply contains a 50/60 Hz transformer to provide the necessary isolation between the mains and the DC output. This transformer has a laminated steel core that needs to be fairly massive in order to provide an adequate impedance to the line voltage.

What is an outdoor Uninterruptible Power Supply?

An outdoor Uninterruptible Power Supply is a power solution designed for critical applications where it's essential that equipment stays running in harsh outdoor environments and significant temperature variations, where an ordinary UPS would fail. Trust TSi Power for these applications.

How does a light power supply work?

A "light" power supply uses active electronics to convert the line frequency to a much higher frequency (on the order of 20 to 100 kHz). This allows the isolation to be achieved with a much smaller transformer that has a powdered ferrite core.

What is the difference between a linear and a switching power supply?

The right one is a linear power supply, the left is a switching power supply. Older adapters were linear, with switching power supply the transformer in the adapter can be smaller. A "heavy" power supply contains a 50/60 Hz transformer to provide the necessary isolation between the mains and the DC output.

Are regulated and unregulated power supplies interchangeable?

As long as the output ratings are compatible (same voltage, same or higher current rating), they're mostly interchangeable. Beware of the difference between regulated and unregulated power supplies.

What is the difference between a light power supply and a transformer?
