300 × 300 mm, 220 V, 500 W adhesive flexible silicone heater for bonding beneath a compatible aluminium plate. It is wired with approximately 1 m leads and a 100K NTC sensor using an XH2.54 connector.
Mains voltage: installation requires a qualified person, suitable AC switching, electrical protection, protective earth on the metal plate and an independent thermal cut-out. It does not connect directly to a 12/24 V bed output.
Electrical data
- Size: 300 × 300 mm.
- Rating: 220 V AC, 500 W.
- Calculated at 220 V: 2.27 A and 96.8 Ω.
- At 230 V and the calculated resistance: approximately 547 W.
- Sensor: 100K NTC 3950.
- Weight: approximately 243 g.
Required protection
- AC SSR or contactor rated for a resistive load with thermal margin.
- Correct fuse/breaker and residual-current protection.
- Independent protective earth on the aluminium plate.
- Non-resettable thermal fuse in contact with the plate and in series with the heater.
- Mains enclosure, segregation, strain relief and temperature-rated wiring.
The SSR-40DA is a candidate AC switch, but usable current depends on temperature and heatsinking; its 40 A marking is not a design guarantee.
Installation
- Verify size, resistance and insulation before bonding.
- Bond once to a clean, flat aluminium plate without bubbles.
- Never cut, drill, fold or crease the pad.
- Fit earth and thermal fuse before power-up.
- Enable thermal protection and suitable slow-cycle SSR control.
- Heat gradually under supervision and compare multiple points with an independent instrument.
It is for you if
- You are building a 300 mm bed and can implement mains safety correctly.
It is not for you if
- You need a heater that plugs into a 24 V board output.
- You cannot provide earth, thermal fuse and mains protection.
