Old Sterling Battery Charger

[Dino]

Hi,
I recently bought a Broom 37 Continental and it is fitted with an old Sterling 24V 15A battery charger power pack. I have attached a photo. Can anyone help identify the model? I can't find any nameplate badge on the unit.
Are these units any good?
One weird thing I have discovered is that I have two shorepower plugs. One feeds the 240V sockets and the other feeds this charger.

Give Sterling a call, and send them your pic. They are always very helpful.

You get what you pay for with chargers, Sterling ok but not anywhere near the best, if going for a new one I would fit a Victron

Thanks folks, I sent a pic to Sterling with a few questions. Got a very brief response saying they have no manual and that the unit must be over 20 years old. I guess they are only interested in people buying new kit.
I'll keep it for this season but I may upgrade it over the winter.
