Output
The output provides an SELV/PELV nominal voltage that is electrically isolated from the input voltage.
The output is designed to supply any type of load, including capacitive and inductive loads. Capacitive loads should not exceed 5500µF with 3.8A or 7000µF with 1.9A additional current load.
In the event of severe overload (if the output voltage drops below 14V) the power supply delivers a continuous output current for 20ms. The output is then switched off for approx. 160ms before a new start attempt is automatically made. This cycle is repeated as long as the overload exists. The device starts operating normally again once the overload has been rectified.
Output voltage | Nom. | 24V |
|
Adjustment range | Min. | 24-28V | Guaranteed value |
Max. | 29.5V | This is the maximum output voltage that can occur in the end position of the potentiometer in clockwise direction due to tolerances. It is not a guaranteed value that can be achieved. | |
Factory settings | Typ. | 24.1V | ±0.2%, at full load (cold device) |
Line regulation | Max. | 10mV | Between 90 and 300Vac |
Load regulation | Max. | 100mV | Between 0 and 3.8A, static value, see Fig. Output voltage over output current, typ. |
Residual ripple and ripple voltage | Max. | 100mVss | Bandwidth 20 Hz to 20 MHz, 50 Ohm |
Output current | Nom. | 3.8A | At 24 V and ambient temperature below 60°C |
Nom. | 3.2A | At 24V and 70°C ambient temperature. | |
Nom. | 2.8A | At 28 V and ambient temperature below 60°C | |
Nom. | 2.4A | At 28 V and 70°C ambient temperature | |
Overload protection | Yes | Electronic protection against open circuit, overload, and short circuit. In the event of a protection event, audible noises may occur. | |
Overload characteristics |
| Continuous current | Output voltage > 14Vdc, see Fig. Output voltage over output current, typ. |
| Hiccup mode | Output voltage < 14Vdc, see Fig. Output voltage over output current, typ. | |
Overload/short circuit current | Max. | 6.7A | Continuous current, see Fig. Output voltage over output current, typ. |
Typ. | 8.6A | Intermittent current peak value for typ. 20ms | |
Max. | 3.2A | intermittent mean current value (rms.) | |
Output capacity | Typ. | 1600μF | Included in the power supply |
Load feedback | Max. | 35 V | The device is resistant and does not show any malfunction when a load feeds back voltage to the power supply. It does not matter whether the power supply is switched on or off. The absorbed energy can be calculated by means of the built-in large-size output capacitor. |
