Replacement AC Adapter for DieHard UPS

This ABLEGRID 17 V AC adapter replaces the original charger for DieHard UPS units carrying part numbers 71988, 200.71988, 28.71988 and 220.71488. It delivers a DC output through a barrel tip connector and is built as a non-OEM alternative that matches the factory voltage specification. The unit is intended for users who need a direct replacement power supply for compatible backup battery systems.

Thermal and Electrical Behaviour

The adapter accepts a universal AC input range of 100 to 240 V at 50 to 60 Hz, making it suitable for worldwide mains supplies. Integrated over-voltage and over-heat protection circuits guard the connected UPS and the adapter itself during extended charging sessions. No active cooling fan is mentioned, so heat is dissipated passively through the enclosure during normal operation.

Included Accessories and Certifications

The package contains one new AC-to-DC adapter charger and no additional cables or mounting hardware. The product carries CE, FCC and RoHS certifications, confirming compliance with common safety and environmental standards. Buyers must verify that the barrel tip size and DC output polarity match their specific UPS unit before connecting the adapter.

Questions about this item

How do I install the ABLEGRID 17V AC adapter for my DieHard 71988 UPS, and what step do people often get wrong?

Connect the barrel tip to the UPS DC input first, then plug the AC cord into a 100-240V 50-60Hz outlet. The common mistake is reversing this order, which can cause a spark at the connector.

What maintenance or replacement will this charger need later?

No routine maintenance is required. Keep the unit ventilated and away from humidity during long use. Replace the adapter if the barrel tip becomes loose, the cable frays, or the over-voltage and over-heat protections activate repeatedly.

What limit appears first when this adapter runs continuously under load?

The over-heat protection triggers first during sustained operation. Ensure adequate airflow around the charger and do not place it on soft surfaces that block ventilation. If it shuts down, let it cool before restarting.
