350 × 350 mm, 220 V, 750 W adhesive silicone heater for large-format 3D-printer beds, wired with approximately 1 m leads and an XH2.54 100K NTC.
Mains voltage: requires professional installation, AC switching, fuse/breaker, RCD, protective earth and an independent thermal fuse. It cannot be driven directly by a 12/24 V bed MOSFET.
Specifications
- 350 × 350 mm; 220 V AC, 750 W.
- Calculated at 220 V: 3.41 A and 64.5 Ω.
- Approximately 821 W at 230 V if resistance remains unchanged.
- 100K NTC 3950.
- Approximately 325 g.
Safe installation
- AC SSR/contactor with genuine margin and suitable cooling.
- Correct fuse/breaker and RCD.
- Independent protective earth on the plate.
- Non-resettable thermal fuse in series near the hottest area.
- Mains enclosure, segregation, strain relief and rated cable.
A correctly sized and cooled SSR-40DA may control it. Since an SSR can fail closed, the thermal cut-out must interrupt mains independently.
Assembly and firmware
- Verify resistance and insulation before bonding.
- Bond once to flat, clean aluminium; never cut or drill.
- Install earth, thermal fuse and cable strain relief.
- Enable thermal runaway protection and slow-cycle SSR-compatible control.
- Commission in stages and compare several plate points with an independent instrument.
It is for you if
- You need a powerful 350 mm bed and can build the complete safe electrical system.
It is not for you if
- You need low voltage or an installation without independent protection.
