Transformers
Maximum Length Maximum single amp circuit run before refeeding
The maximum capacity of a system must not exceed 25 amps. Maximum total wattage is 600W at 24V and 300W at 12V. Run lengths exceeding these limitations require multiple fixtures, each with independent feed running to the transformer.
| Maximum Length Chart (25 amps) | |||
| Lamp Code | Volts/Watts | Max lamps | Max length |
| XF12V3W | 12V 3W | 100 | 18 ft 10 in |
| XF12V5W | 12V 5W | 60 | 11 ft 4 in |
| XF24V3W | 24V 3W | 200 | 37 ft 8 in |
| XF24V5W | 24V 5W | 120 | 22 ft 8 in |
| To determine the required quantity of feeds: | Example: |
| 1. Add up total Flex Strip length in feet | (Ft. of Flex Strip) 100 |
| 2. Multiply by 5.3 (lamp sockets per foot) | x5.3 = 530 |
| 3. Multiply result by watts per chosen lamp | (3W) x3 = 1,590 |
| 4. Divide by maximum total wattage | (24V ) 600 = 2.3 |
| 5. Round up to next whole number | = 3 |
| See transformers listed below. | (Three 600W feeds required) |
