Power Supplies
Switch-mode AC-DC supplies that run 12 V and 24 V radio equipment from mains — lighter, cooler and quieter than the linear supplies they replace.

5 models in this range from Samlex.
Switch-Mode Power Supply — 13.8 V / 23 A
A switch-mode bench supply for running 12 V radio equipment from mains. Switch-mode construction keeps it far lighter and cooler than the linear supplies it replaces, which matters when it lives on a desk beside the operator.
Specifications
Key Features
- Sized for a 25 W mobile transceiver on continuous duty
- Low weight and bulk compared with a linear supply
- Fan runs only as temperature demands, keeping it quiet
- Short-circuit protection
- Overload and over-temperature protection
- Reverse-polarity protection
Switch-Mode Power Supply — 13.8 V / 30 A
The 30 A model in the G series, for a 50 W mobile transceiver or a small multi-radio bench. Ripple is held under 150 mV peak-to-peak, which keeps receiver noise down — the usual failing of cheap switch-mode supplies.
Specifications
Key Features
- 30 A continuous — suits a 50 W mobile at full transmit
- Under 150 mV ripple keeps receiver noise low
- Current limiting at 35 A before shutdown
- Short-circuit protection
- Overload and over-temperature protection
- Reverse-polarity protection
Switch-Mode Power Supply — 27.6 V / 10 A
The 24 V member of the G series, for equipment built around a 24 V vehicle or marine system — commercial vehicle radios, marine electronics, and industrial gear that will not run from 13.8 V.
Specifications
Key Features
- 27.6 V output for 24 V system equipment
- Bench-powers marine and commercial vehicle radios
- Wide 115–230 V input accepts either mains standard
- Short-circuit protection
- Overload and over-temperature protection
- Reverse-polarity protection
Premium Power Supply with Analogue Meters
The premium desktop supply, designed specifically for land mobile radio. Power-factor corrected and certified to IEC 62368-1, with backlit dual analogue meters so voltage and current draw are visible at a glance rather than guessed at.
Specifications
Key Features
- Backlit dual analogue meters show volts and amps live
- Universal 100–240 V input works on any mains standard worldwide
- Power factor corrected — lighter, quieter, more efficient
- Certified to the current IEC 62368-1 safety standard
- Designed specifically for land mobile radio duty
- Short-circuit protection
- Overload and over-temperature protection
Rack-Mount Power Supply — 40 A
A 40 A rack-mounting supply for equipment rooms and base-station cabinets, where the supply belongs in the rack with the repeater rather than on a shelf beside it.
Specifications
Key Features
- Rack-mount format suits base station and repeater cabinets
- 40 A supports a repeater plus ancillary equipment
- Built for continuous unattended operation
- Short-circuit protection
- Overload and over-temperature protection
- Reverse-polarity protection
