Your info is somewhat confusing. First, does PI even make just a surge suppressor? I have a PI EMS and it displays error codes. Second, an EMS or surge suppressor does not replace a converter. They're 2 totally different pieces of equipment. The converter keeps your 12v batteries charged. The EMS monitors incoming AC current and cuts off when necessary.
I agree he is confused.
Yes Progressive Industries makes Surge Supressors (Energy Monitor Systems) like the HW-50C
Progressive DYNAMICS makes converters Intella Power 9200 line for example...WFCO also makes Converters. not as good as PD's.
So he replaced a CONVERTER with a Surge Supressor? What is he doing for 12 volts.
Now: Surge Protectors (top end units like the HW-50/30c) contain a deice called a solenoid Basically a big, heavy Relay (Relays.
Small ones are called "relays" Medium "Solenoid" And truly big jobbers "Contactors" all same device save for size)
IF the coil is fed AC it can buzz.
Also the core of both the Solenoid magnet and any transformers for 60HZ will be made up of metal leaves and varnish..Leaf after leaf is coated with varnish and the next leaf applied on top of it.
If the varnish dries BUZZZZZZZZZZ
if something prevents the thing from pulling inall the way (Contact is made before travel stopps normally) Say a suicidal bug on the armature or magnet's core.....BUZZZ
And least I forget it the ever famous "Other causes" .
