CS3.241 24V, 3.3A, SINGLE PHASE INPUT C–Series 26. APPLICATION NOTES 26.1. PEAK CURRENT CAPABILITY Solenoids, contactors and pneumatic modules often have a steady state coil and a pick-up coil. The inrush current demand of the pick-up coil is several times higher than the steady state current and usually exceeds the nominal output current (including the PowerBoost) The same situation applies, when starting a capacitive load. Branch circuits are often protected with circuit breakers or fuses.
PAGE 18
CS3.241 24V, 3.3A, SINGLE PHASE INPUT C–Series 26.4. OUTPUT CIRCUIT BREAKERS Standard miniature circuit breakers (MCBs) can be used for branch protection. Ensure that the MCB is rated for DC voltage, too. The following tests show which circuit breakers the power supply typically trips. Circuit breakers have large tolerances in their tripping behavior. Therefore, these typical tests can only be used as a recommendation or for comparing two different power supplies.

CS3.241 24V, 3.3A, SINGLE PHASE INPUT C–Series 26.6. SERIES OPERATION The power supply can be put in series to increase the output voltage. Fig. 26-5 Schematic for series operation Unit A AC DC + + Unit B AC DC Load + - Earth Instructions for use in series: a) It is possible to connect as many units in series as needed, providing the sum of the output voltage does not exceed 150Vdc. b) Voltages with a potential above 60Vdc are not SELV any more and can be dangerous.

CS3.241 24V, 3.3A, SINGLE PHASE INPUT C–Series 26.9. EXTERNAL INPUT PROTECTION The unit is tested and approved for branch circuits up to 20A. External protection is only required if the supplying branch has an ampacity greater than this. In some countries local regulations might apply. Check also local codes and requirements. If an external protective device is utilized, a minimum value is required to avoid undesired tripping of the fuse. Ampacity max. min.

CS3.241 24V, 3.3A, SINGLE PHASE INPUT C–Series 26.12. MOUNTING ORIENTATIONS Mounting orientations other than input terminals on the bottom and output on the top require a reduction in continuous output power or a limitation in the max. allowed ambient temperature. The amount of reduction influences the lifetime expectancy of the power supply. Therefore, two different derating curves for continuous operation can be found below: Curve A1 Curve A2 Recommended output current.
