Note: The DC-ok feature requires that the output voltage reaches the nominal (=adjusted) level after turn-on in order to function according to specification. If this level cannot be achieved, the overload LED will be on and the DC-ok contact will be open. The overload signal will only shut off as soon as the adjusted voltage is reached. This is an important condition to consider particularly, if the load is a battery, the power supply is used in parallel or the power supply is used for N+1 redundant systems.
Restrictions apply when using the DC-OK contact in a Haz-Loc environment: The DC-OK contact is intended to be used for a separately investigated nonincendive field wiring and/or field wiring apparatus. The apparatus may be located in a Class I, Division 2 (Group A, B, C or D) hazardous (classified) location. Non associated nonincendive field wiring apparatus shall not be connected in parallel unless this is permitted by the associated nonincendive field wiring apparatus approval.
The Lifetime expectancy shown in the table indicates the operating hours (service life) and is determined by the lifetime expectancy of the built-in electrolytic capacitors. Lifetime expectancy is specified in operational hours. Lifetime expectancy is calculated according to the capacitor’s manufacturer specification. The prediction model allows a calculation of up to 15 years from date of shipment. MTBF stands for Mean Time Between Failure, which is calculated according to statistical device failures, and indicates reliability of a device. It is the statistical representation of the likelihood of the unit to fail and does not necessarily represent the life of a product.
