Power supplies & chargers for amateur radio
Amateur Radio kit lives or dies by the quality of its DC rails. Receiver noise floors on HF (1.8–30 MHz) sit only a few dB above thermal noise, so any switching hash, ripple or earth-loop hum shows up immediately as S-meter creep and degraded weak-signal copy. The Mascot range gives you two paths: traditional linear AC/DC supplies (8421, 6823, 2083, 2183) where every watt of receive sensitivity counts, and quiet filtered switch-mode units for QRP, portable and digital-mode work where weight and efficiency dominate. For the battery side of the station - handheld NiMH packs, SLA station batteries and modern LiFePO4 portable packs - Mascot's 2040, 2240, 8314 and 4040 chargers cover everything from 60 mA trickle to 5 A bulk, with the correct chemistry profile in every case. Everything ships from UK stock at Pulsar Developments with the CE/UKCA paperwork your club station or club exam centre may need.
Read the guideMarine & Leisure battery chargers
Marine installations punish chargers harder than almost any other application - salt air, condensation, vibration from the engine room and long unattended float-charge cycles. A consumer-grade charger that survives in a garage will corrode and fail in a wet bilge in a single season. The Mascot range is built specifically for this duty: sealed cases, vibration-tolerant construction, IEC mains entry that can take a sealed inlet, and 3-stage profiles (bulk → absorption → float) tuned for marine AGM, gel, flooded lead-acid and LiFePO4 chemistries. Current-detection circuitry on the 4340 and 4040 ranges lets the charger safely restart on a deeply discharged bank without back-feeding through a sleeping BMS. Pick the 2040 / 2041 / 2240 series for 12V banks up to 100Ah, the 2440 and 4040 series for 24V banks and larger leisure installs, and the 4040 LiFePO4 chargers (4 to 16 cells in series) for modern lithium leisure batteries.

A modern motorhome electrical system juggles three energy sources - 230V hookup at site, the alternator while you drive, and the leisure battery (or batteries) when you're off-grid. Getting the three to cooperate without flattening the starter battery, cooking the leisure bank or browning out the kettle takes the right mix of charger, DC/DC converter and inverter. The Mascot range covers all three: 2040/2041 and 4040 hookup chargers for SLA, AGM and LiFePO4 leisure banks; 9970 and 8662/9261 DC/DC converters to keep a sensitive 12V rail (TV, satellite receiver, CPAP, fridge electronics) stable when the leisure battery sags to 11.8V under load; and the 2284 / 2285 / 2286 / 2287 pure sine-wave inverter family from 150W to 1000W for laptops, microwaves and induction kit. Every inverter is offered in both 12V and 24V input variants and with UK or EU output sockets - pick the version that matches your install rather than reaching for an adaptor.

Equipment used in clinical environments falls into two distinct regulatory buckets, and choosing the right power supply depends on which bucket your device sits in. Devices in direct patient contact (BF/CF applied parts under IEC/EN 60601-1) require certified medical supplies with 2× MOPP isolation, leakage current below 100 µA and full Declaration of Conformity paperwork. These are a specialist line we can supply to order from the wider Mascot catalogue with full documentation. The much larger group of medical-adjacent equipment - dental compressors, lab analysers, sterilisers, vet diagnostics, pharmacy fridges, hospital admin and signage - typically sits behind a Class I or Class II AC inlet without a patient-contact requirement, and is well served by the standard Mascot linear and switch-mode range. Class II construction (no protective-earth dependency), wide-input AC, very low ripple and the documentation trail Mascot supplies as standard make them a sensible default. If you specifically need an IEC 60601-1 certified unit with a 2× MOPP declaration, contact us on 01189 795319 - we can quote against the relevant Mascot certified-medical Model on a project basis.
Read the guide24V power supplies for industrial control panels
Industrial control cabinets are the unglamorous workhorses of the built environment - every conveyor, lift, HVAC system, packaging line and process skid depends on one. The supplies inside have to tolerate the worst of factory life: ambient temperature swings, vibration, inductive load spikes from contactors and solenoids, voltage transients on the mains and the occasional short-circuit from a field installer's wrong wiring. The Mascot industrial range gives you a clean 24V DC rail at the current you need, from the compact 9726 (72W) for a small sensor-only panel through the 3220 (101W) and 3820 (120W) for a typical small machine, up to the heavy 8921 (290W) and 2225 (588W) for VFD drive-cabinet auxiliaries and multi-axis equipment. The Blueline 3520 (265W) and 3920 (180W) variants meet DoE Level VI and CoC Tier 2 efficiency for European panel exports. Every model is short-circuit and overload protected, recovers automatically when the fault clears, and accepts a wide 90–264V AC input so a single panel design ships globally.
Read the guideLow-noise linear PSUs for broadcast, studio & professional AV
Studio and AV racks are unforgiving of dirty power. Any hum, switching artefact or ground loop shows up immediately as 50 Hz buzz on a mixing console, banding on a video monitor or HF hash on a wireless mic receiver. The Mascot linear range is built specifically for this work: fully linear AC/DC with a conventional 50 Hz transformer, traditional rectifier and series-pass regulator, so the only ripple on the output is a small 100 Hz residual that's easy to filter and inaudible. The 2083 (10–24W) and 2183 (24W) plug-top series suit individual outboard, DI boxes and small wireless receivers; the 8421 (36W variable 5–15V or 12–30V), 6823 (1A linear) and 8937 (5–24V) give you bench-style adjustable output for retrofits and one-off racks. For 24V studio rigs that need to derive a clean 13.5V phantom rail, the linear DC/DC 8662 (80W) and 9261 (110W) do the job without introducing a single switching edge into the signal chain.
Read the guideLithium pack chargers for EV conversions and light traction
Light-EV, mobility and traction packs need chargers matched precisely to the cell count and chemistry of the pack. The wrong charger won't just under-charge - it will sit at the wrong per-cell voltage and either trip the BMS into permanent fault or, on Li-Ion, overcharge the top cells until thermal runaway becomes a real risk. The Mascot range removes the guesswork by listing the cell count explicitly in every Model: the 4340 family (87W, ~3A typical) covers 3–6 cells of Li-Ion and 4 or 8 cells of LiFePO4 for small e-bike and mobility packs; the 4040 family (191W, ~8A typical) covers 4, 8 and 16 cells of LiFePO4 and the 8–14 cell Li-Ion range for larger traction packs; the 3540LiFe series (285W, 5–10A) is the heavy hitter for 7, 9 and 16-cell LiFePO4 conversion packs. Every charger uses constant-current then constant-voltage termination - never a lead-acid-style float - and includes current detection so a deeply discharged pack restarts cleanly through its BMS.
Read the guideLinear and switch-mode bench supplies for test & R&D
A lab bench needs supplies that are accurate, well-regulated, protected against the inevitable accidental shorts, and quiet enough not to contaminate sensitive measurements. The Mascot linear range is exactly the right tool for analogue, RF and low-noise prototyping work: the 8421 (36W, switchable 5–15V or 12–30V), 6823 (5V/2A, 6–12V/1A and 12–24V/0.5A linear variants) and 8937 (5–24V, 18W) give you adjustable bench rails with cleaner output than any switching unit can match. For higher-current digital prototyping where ripple matters less, the standard switch-mode Mascot range gives you 12V or 24V at 100W and up at a fraction of the size and weight. Pair either with a current-limited bench supply and a dummy load and you have a complete characterisation setup.
