CAUTION: Hazardous internal voltages and high temperatures.
Ensure that unit is not user accessible.
OUTPUT
True latching OVP is available as an option. Please add the suffix ‘-V’ to the
model number, e.g. EXA40-24S1V8-V. Additional alphanumeric suffixes
maybe added to indicate minor modifications not affecting the safety
approvals.
Guaranteed minimum output voltage range.
Latching OVP response time is 1ms (typical). OVP latch is reset by toggling
remote ON/OFF or by recycling the input voltage.
Figures are percentage of minimum input voltage.
Rshort ≤20mΩ.
TVS spec : 6V8 @ 10mA, 10V5 @ 57A
Maximum continuous output power.
40 Watts for S05 models
26.4 Watts for S3V3 models
22 Watts for S2V75 models
14.4 Watts for S1V8 models.
User must provide recommended fuses in order to comply with safety
approvals.
