Samlex — Power Supplies
Switch-mode AC-DC supplies, isolated and step-down DC-DC converters, battery backup modules, and multi-stage chargers.
Samlex — Power Supplies, Converters & Backup
Samlex builds the power side of a radio installation: switch-mode AC-DC supplies for bench and rack, step-down and galvanically isolated DC-DC converters for running 12 V equipment from 24 V vehicles and vessels, battery backup modules that keep a base station alive through a mains failure, and multi-stage battery chargers.

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
Battery Backup1 product
Battery Backup Module — 12 V / 24 V
Sits between a power supply and the radio, switching seamlessly to a battery when mains fails. For a base station carrying emergency traffic, this is the difference between a site that stays up in a power cut and one that does not.
Specifications
Key Features
- Automatic changeover to battery when mains power fails
- Selectable for 12 V or 24 V systems
- 31 A capability on a 12 V system
- Also functions as a battery isolator
- Pairs directly with Samlex SEC power supplies
- Essential for base stations carrying emergency traffic
Step-Down DC-DC Converters2 products
Step-Down DC-DC Converter — 24 V to 13.8 V / 8 A
Runs 12 V radio equipment from a 24 V vehicle system — the standard problem on trucks, buses, and commercial vessels. The separate 100 mA memory-backup output keeps radio presets alive when the main output is switched off.
Specifications
Key Features
- Dedicated memory-backup output preserves radio presets
- Runs 12 V radios from 24 V trucks, buses, and vessels
- High switch-mode efficiency, little waste heat
- Short-circuit, reverse-polarity, and overvoltage protection
- Compact enough to mount behind a dashboard
Step-Down DC-DC Converter — 24 V to 13.8 V / 20 A
The higher-current step-down converter, at 20 A. Enough headroom to run a 50 W mobile transceiver at full transmit from a 24 V vehicle system rather than a handheld-class load.
Specifications
Key Features
- 20 A handles a 50 W mobile transceiver at full transmit
- Tight ±0.1 V output regulation
- Compact and light for its current rating
- Current-limit circuitry protects the converter
- Short-circuit, reverse-polarity, and overvoltage protection
Isolated DC-DC Converters5 products
Isolated DC-DC Converter — 100 W, 12.5 V / 8 A
Galvanic isolation between input and output, which breaks the ground loop that causes alternator whine and hum on vehicle and marine installations. The fix when a non-isolated converter leaves noise on the audio.
Specifications
Key Features
- Galvanic isolation eliminates ground-loop noise
- Foldback current limiting protects under overload
- Compact housing for tight installations
- Protected against short circuit, overheating, overvoltage, and reverse polarity
Isolated DC-DC Converter — 200 W, 12.5 V / 16 A
The 200 W isolated converter at 12.5 V, delivering 16 A. Twice the capacity of the IDC-100 for the same isolation benefit, where a single radio is not the only load on the output.
Specifications
Key Features
- 16 A of isolated 12 V supply from a 24 V system
- Galvanic isolation removes ground-loop interference
- Foldback current limiting
- Compact housing
- Short-circuit, overheat, overvoltage, and reverse-polarity protected
Isolated DC-DC Converter — 200 W, 24.5 V / 8 A
The 24 V output member of the 200 W family. Used where isolation is needed but the equipment runs at 24 V — providing a clean, separately grounded 24 V rail rather than stepping down to 12 V.
Specifications
Key Features
- Isolated 24 V output rather than a step-down to 12 V
- Breaks ground loops between vehicle and equipment
- Foldback current limiting
- Compact housing
- Short-circuit, overheat, overvoltage, and reverse-polarity protected
Isolated DC-DC Converter — 360 W, 12.5 V / 30 A
The largest isolated converter in the range at 360 W, giving 30 A of clean 12 V from a 24 V system. Sized for a full vehicle installation — radio, amplifier, and ancillaries together.
Specifications
Key Features
- 30 A isolated output — a whole vehicle installation on one converter
- Galvanic isolation across the full 360 W
- Foldback current limiting
- Protected against short circuit, overheat, overvoltage, reverse polarity
Isolated DC-DC Converter — 360 W, 60–120 V Input
Same 360 W and 30 A output as the B model, but fed from a 60–120 V DC input. That suits traction and industrial DC systems — rail vehicles and telecom plant — where the supply rail is far above vehicle voltage.
Specifications
Key Features
- Accepts 60–120 V DC — rail traction and industrial DC plant
- 30 A of isolated, regulated 12 V output
- Galvanic isolation from a high-voltage DC rail
- Foldback current limiting
- Short-circuit, overheat, overvoltage, reverse-polarity protected
Battery Chargers1 product
4-Stage Battery Charger — 12 V / 15 A
A fully automatic four-stage charger for 12 V lead-acid and lithium batteries, able to charge two separate banks. A DIP switch converts it to a two-stage algorithm so it can charge a battery while a DC load draws from it — effectively a DC UPS.
Specifications
Key Features
- Charges flooded, AGM, gel, and lithium batteries
- Two-stage DIP setting supports DC UPS operation under load
- Charges up to two separate battery banks
- Can double as a plain DC power supply
- Overload and short-circuit protection
