A PDLC installation consists of three parts: the film/glass, a driver or transformer that converts mains power (100–240 V) into the right alternating voltage, and the controls.
- Sizing the transformer: add up the area (m² or ft²) and use the stated power per m² plus a margin. Electrically, PDLC film behaves like a capacitor; larger areas need a driver with sufficient capacity.
- Controls: wall switch, RF remote, Wi-Fi/Tuya module with app, voice assistant, or a dry contact/relay for home automation (KNX, Zigbee, Z-Wave, Home Assistant).
- Dimming: only with a driver designed for it – a regular light dimmer on the mains side is not meant for PDLC.
- Groups: several windows on one driver switch together (as in the demo on the home page); one channel per zone gives more flexibility.
Safety: the mains side must be connected by a qualified electrician according to local regulations (e.g. IEC 60364, the NEC in the USA or BS 7671 in the UK). Never use DC and never connect the film directly to mains power. [26]
