Alpha 1000 Handbook
Output Connections:
Output Connector Ratings:
1. 6.35mm fastons are rated at 15A.
2. 9.5mm Faston terminals are rated at 32A (Tab thickness = 1.0mm, suitable Faston terminals are AMP
151667-2 or AMP 280223-2
3. M5 screw terminals are rated at 100A subject to the wire and wire connector used to connect them.
Maximum recommended torque setting for M5 screws is 2.4 – 2.6Nm.
Adjustment and Derating:
The Alpha 1000 series is designed to provide a max output power of 1000W at nominal output voltages. The
following procedure must be used to ensure the PSU is operated within its ratings:
1. Calculate the output power for each module (Volts x Amps).
2. Total power for slots 1-3 must be ≤720W. Total power for slots 4-7 must be ≤ 600W. Total power (slots 1-7)
must not exceed value stipulated in unit limitations table
3. Calculate the ampere turns (Amps x turns) for each module.
4. Add total ampere turns: Slots 1-3 ≤120. Slots 4-7 ≤120. Total of slots 1-7 ≤ 200AT
