24V 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.
What to look for
- 24V nominal output, regulated within ±2% under load step (the standard for European PLC kit)
- Continuous current matched to total panel load × 1.3 for headroom (24V × 5A = 120W is the sweet spot for a small machine)
- Industrial temperature rating - Mascot industrial supplies operate from -25 °C to +60 °C without derating
- Overload and short-circuit protection with auto-recovery - a tripped supply that needs a power cycle is a service call you don't want
- Wide AC input (90–264V) so the panel can ship to North America, Europe and Asia without a hardware change
- DoE Level VI / CoC Tier 2 efficiency on Blueline models for European energy-labelled equipment

- How do I size a supply for a control panel?
- Add up the steady-state 24V loads (PLC + I/O + relays held in + sensors), multiply by 1.3 for headroom, then round up to the next standard rating. Don't size on inrush alone - Mascot industrial supplies tolerate brief 150% overloads, which covers contactor pull-in transients without needing a giant supply. A typical small machine sits at 100–150W; reach for the 588W 2225 only when you're running a VFD's 24V control rail at scale.
- Do I need an isolated DC/DC for sensor rails?
- Worth it when you have analogue 4–20 mA sensors sharing a supply with relays, contactors or a VFD. Isolation breaks ground loops and stops switching noise from corrupting the measurement. The Mascot DC/DC converter range gives you a clean second 24V rail from the same primary supply.
- Why pick a Blueline supply over the standard range?
- The Blueline 3520 / 3920 / 3820 family meets DoE Level VI and CoC Tier 2 efficiency, which is mandatory for many European energy-labelled finished products and is a tick-box requirement for some larger OEM customers. They're also typically a little more compact for the same wattage.
- Can I mount the supply on a DIN rail?
- The Mascot industrial range is primarily chassis / footprint mount with an IEC inlet, which suits a typical European enclosure layout. For dedicated DIN-rail mounting in a tight panel we can supply DIN brackets to order - call 01189 795319 with the Model and we'll confirm the right adaptor.
