[1] Duty Cycle: Currents <11 A may be provided continuously. For currents > 11 A, see Figure B. The current may be provided 60-T-
I minutes any 60 minute period where T is the temperature in °C (room temperature is about 23 °C) and I is the output current in
Amps. For example, 17 A, at 23 °C could be provided for 60-23-17 = 20 minutes each hour. When the 5520A is outputting
currents between 5 and 11 amps for long periods, the internal self-heating reduces the duty cycle. Under those conditions, the
allowable "on" time indicated by the formula and Figure B is achieved only after the 5520A is outputting currents <5 A for the "off"
period first.
[2] For currents >11 A, Floor specification is 4000 μA within 30 seconds of selecting operate. For operating times >30 seconds, the
floor specification is 2000 μA.
[3] For currents >11 A, Floor specification is 10000 μA within 30 seconds of selecting operate. For operating times >30 seconds, the
floor specification is 5000 μA.
