- Page 3 6: Over Current Protection ( OCP ) The DCW300 / 500 employ a constant current with hiccup mode ( over load / short circuit ) protection. At approximately 60% of the output voltage, the unit operates in constant current mode and then enters hiccup mode for short circuit protection.
- Page 4 9: Connections: The connection details illustrated in Fig 9-1 is of a typical standard model and it may vary from unit to unit and or design. DC Input: + - & Earth Alarm: The units are supplied with a Power Fail Alarm.
- Page 5 11: Parallel Operation of two units: The DCW300 / 500 units have built-in output isolation diodes that allow two units ( maximum ) to be connected in parallel for N+1 Redundancy applications. This ensures that the output power to the load is available, in the event one of the units should fail.
- Page 6 12: Series Operation of two units: The DCW300 / 500 units can be connected in series as per Fig 12.1. This allows for example two 24V output models to be connected in series for 48V output. Output diodes to prevent reverse voltage applied to each unit under certain conditions.
