Table for selecting the recommended 12 V DC power source
To select a suitable source, allow a margin of 30% (due to start-up, line losses and operation in cold conditions). Calculation: Cable power P = 15 W/m × length (m). Current I = P / 12 V. Recommended source: Psource = P × 1.30 and Isource = I × 1.30.
1 m: P = 15 W, I = 1.25 A, recommendation (30% reserve): 19.50 W / 1.63 A 12 V DC 2 A (24 W) power supply or stronger
2 m: P = 30 W, I = 2.50 A, recommendation (30% reserve): 39.00 W / 3.25 A 12 V DC 4 A (48 W) power supply or stronger
3 m: P = 45 W, I = 3.75 A, recommendation (30% reserve): 58.50 W / 4.88 A 12 V DC 5 A (60 W) power supply or stronger
4 m: P = 60 W, I = 5.00 A, recommendation (30% reserve): 78.00 W / 6.50 A 12 V DC 8 A (96 W) power supply or stronger
5 m: P = 75 W, I = 6.25 A, recommendation (30% reserve): 97.50 W / 8.13 A 12 V DC 10 A (120 W) power supply or stronger
Installation and sizing recommendations
Power supply: use a stabilized 12 V DC power supply with sufficient current according to the table.
Cables: for longer connections, choose a larger cross-section of the cables due to voltage drop (lower voltage means lower heating output).
Protection: a fuse or circuit breaker on the DC side is recommended depending on the selected source current.
For demanding conditions: for outdoor installation and very low temperatures, it is advisable to choose a power source with a higher power class.
