Performance Curves
Performance Curve
Diagram Description: A graph showing the percentage of maximum load (Y-axis) versus surrounding air temperature in °C (X-axis). Curve 1 represents Position A, showing full load capacity up to approximately 45°C. Curve 2 represents Positions B + C, showing reduced load capacity at higher temperatures.

Connections and Schema
Correct Parallel Connection
Diagram Description: Illustrates two ABL1A... power supplies connected in parallel. Input lines L, N, PE are connected to both units. Output lines L1 and L2 are connected from each unit to the load. Condition for correct parallel connection: L1 = L2.
Incorrect Parallel Connection
Diagram Description: Illustrates an incorrect parallel connection where output lines L1 and L2 are not equal. Conditions for correct parallel connection are stated: max 2 x ABLx1Axxxxx, L1 = L2, AV max 25 mV, Load < 90% 2 x Inom.
Output Voltage Balancing
Diagram Description: Shows two power supplies (ABL1A...-1 and ABL1A...-2) with their outputs connected in series. The diagram indicates voltage outputs (Vout1, Vout2) and load connections. Requires 2 x Diodes with specific VRRM and IF ratings. The total output voltage (VLoad) is the sum of Vout1 and Vout2. Conditions for series connection: RLoad1 = RLoad2, I = 2 = ~ Inom.
