  • Page 8 RTxxx LED lighting controllers - User Manual The Power Supply Unit (PSU) used to energise the RTxxx must provide double insulation/reinforced isolation from mains electricity and pro- tected against short circuits and overloads. We recommend using a PSU that limits its output current to the appropriate rating of the con- troller by design, by setting the current limit on the supply (if pos- sible), or through over current protection.

  • Page 27: Fault Detection

    RTxxx LED lighting controllers - User Manual The duty cycle is limited by ignoring triggers which are too soon after the previous trigger. For example, if the brightness is set to 250%, then the RTxxx does not allow pulses greater than 10ms long. With 10ms pulses, if a trigger occurs within 50ms of a previous trigger (so that the duty cycle would be greater than 20%) the trigger is ignored.

    RTxxx LED lighting controllers - User Manual 13.2 Restrictions The maximum output power for an RT2xx is 30W per channel or 40W total. For an RT4xx, it's 30W per channel or 50W total. The maximum output power for an RT8xxF is 30W per channel or 100W total. The following timings and restrictions are applied whenever settings are saved (using the AW command).

  • Page 67: Error Codes

    RTxxx LED lighting controllers - User Manual Special note for RT8xxF controllers: If you need to generate a variety of output currents, the highest current loads should be connected to the low-numbered output channels. For example CH1, CH2... This minimises the spread of high currents on the internal PCB and helps to maintain a low temperature rise in the unit.
