Temperature hysteresis of approximately 10°C provided between shutdown and restart.
1. Below -5°C, the rise time is approximately 5 minutes to protect the bulk capacitors.
2. Complies with GR947 which calls for a minimum rise time proportional to output load.
3. On start-up, a 20 second fold-down current limit is activated to permit system start-up when units are plugged in one at a time.
Beyond 20 seconds, hiccup mode of operation with approximately a 10% duty cycle is enabled. A latched mode current limit
can be activated via an I2c command. During hiccup performance the power supply would shut down when the output voltage
falls below 39Vdc.
