Notes
1. For HR301-2805, with the remote sense pins connected to the load and no resistance between the output pins and load.
2. A low output impedance power source is required on the input to realize this start-up time. If less than full surge current is available, start-up time
will be longer
CAUTION
Permanent damage to the HR301-2805 will result if pin 6 is shorted to ground. Damage may also result if pin 4 or pin 5 is disconnected from the load
during operation with the remote sense leads connected to the load. If remote sense pins are not connected to the load, the output voltage of the
HR301-2805 will rise to approximately 6.2 VDC measured across pins 4 and 5.
