TR-RT LED lighting controllers - User Manual
12.2
Restrictions
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 a TR-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
a TR-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 a TR-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.
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%.
