A Light weight 978-100 Amp Power supply  Time owned: 3 to 6 months
I have been using the 978-100 supply for about 4 Months now it is the 100 Amp version, using FIVE 20 amp individual Switching power supplies, and it runs my Complete station.
The Dc Output Measures 13.9vdc, with a 75 amp load from my Ameritron ALS-500 the PS drops only 100 Milli-volts!
When I first received the 978 I noticed that there are no Ferrite Cores to minimize RF Hash.
I installed 6 ferrite sleeve type cores over the incoming AC Mains that go to a terminal an internal AC Terminal block.
The power supply has an internal fan that runs all the time. If one supply fails the rest will still function! Two of the 978-100 may be connected together using a connection between the two on the rear of the units, for 200AMPS!
Each supply is is individually monitored for over voltage and overheating.
Like all switching Power supplies, it is a good idea to keep the PS away from the ANTENNA, to minimize any RF Hash!
The 978 comes in several versions 40.60,80, or 100 AMP. You just keep adding the 20 AMP Modules.
The main AC Plug is a 15 AMP type and will not fit into a normal 120 Volt outlet,as one of the ac prongs is Horizontal, instead of Vertical.
The front panel has 5 Indicator lights that, tell you each module is OK, if a module fails the lamp will flash OFF/ON, lastly there is a QOVERHEAT lamp that glows if a Module gets too hot.
