346 Modular Bulk Power Supply

The 346 modular bulk power supply consists of a 346A1 Power Panel and up to three 346A
Power Units (see Figure 4-12). The panel has three 2-ampere resettable circuit breakers one
for each 346A Power Unit (see Figure 4-13). Power panels are used with one, two, or three
power units connected.
A standard 5-foot (1.52-m) double-ended (male, female) power cord connects the 346A1
Power Panel to an ac outlet. Service to the ac outlet must be a dedicated (nonswitched) 20-
ampere line. A maximum of four power panels can be connected to the 20-ampere line.
Note: The city of Chicago and Cook County Illinois electrical codes require the use of a
fused ac power cord POP-6/217 manufactured by JDS Products and a metallic 346B1
Power Panel.
Each 346A Power Unit provides four power jacks. A slide switch is located between the top
two and bottom two jacks. When the slide switch is in the down position, 10 watts of power
is provided at the jacks above and below the switch.
When the slide switch is in the up position, the power from the jack above the switch and
below the switch are combined. This provides 20 watts of power at the jack above the
switch. The jack below the switch will have no power.
