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).
B.1 Continuous Mode
The maximum output current is 3A (2A for an RTxxx-2).
B.2 Switched Mode
The maximum delay from a trigger input changing to the output
current being turned on or off is 10us. The maximum output current is
20A (2A for an RTxxx-2).
B.3 Selected Mode
The maximum delay from a trigger input changing to the output
current being turned on or off is 5ms. The maximum output current is
0.5A.
B.4 Pulse Mode
The maximum output current is 20A (2A for an RTxxx-2). For high
current pulses the following limits apply:
Pulse current
Pulse length limit
20A
100μs
12A
400μs
10A
1ms
5A
3ms
Pulses of 2A or more for pulse widths longer than 2ms may cause an
error or have a lower current towards the end of the pulse:
For fast pulse controllers (RTxxxF) the minimum pulse delay is about
2µs. When overdriving or using the retrigger delay, the minimum
delay is around 5µs.
For pulse widths less than approximately 150us, the output voltage
and current cannot be measured. Because of this, fault detection is
disabled and the following restrictions apply:
For pulse currents greater than 0.5A, the duty cycle is restricted
to 1%.
For pulse currents less than or equal to 0.5A, the duty cycle
restricted to 10%.
