Alpha 800 Instruction Manual
The total voltage of a seriesed output must not exceed 160Vdc.

If any output or seriesed output is ES2 or ES3 then all the outputs in the PSU must be considered as ES2 or ES3

ES2 and ES3 outputs must be guarded or a deflector fitted during installation to avoid a service engineer making

inadvertent contact with the output terminals, or dropping a tool onto them.
All outputs have operational spacings to earth, and due consideration must be given to this in the end product


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 800 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 user for 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)
not exceeding value stipulated in unit limitations table
3. Calculate user 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
