Full load capability is actually 70 A at 3 V and 60 A at 4 V. The maximum rating of the output pins is 50 A.
Full load capability is actually 140 A at 3 V and 120 A at 4 V. The maximum rating of the output pins is 100 A.
*** Full load capability is actually 75 A. The maximum rating of the output pins is 50 A.
**** Input voltage range is 42 V min to 53 V max.
Notes:
1: Output voltage at 48 Vdc input, no load and 25°C temperature.
2: Maximum power and current ratings should not be exceeded under normal operating conditions.
3: The ending "P" indicates positive enable logic (pull PC pin low to disable). Change to "M" to
indicate negative logic (pull PC pin low to enable).
4: Exceeding this value can cause the unit not to turn on into load.
