1) The first unit is a Siemens L-829 CCR. Model number is PPF 6630, and it is what we call a Powerpack setup. This means that it has no side panels or top, and is designed to slide into a switchgear cabinet.
a. It is considered an “older” unit, but parts are still available from ADB and other aftermarket vendors.
b. It is setup for 480 volt AC, single phase input and 6.6 amp maximum output. It is adjustable to 5 steps of amperage output (lighting steps). Unit capacity is 30kW (the largest common size).
c. This unit does not have a computer monitor and control system attached, but is designed to plug into one.
d. It is missing one component to be fully operational: the printed circuit board to control this regulator, which is called a URC.
e. If you wish to sell this unit at a scrap price, be aware that it weighs in excess of 1000 pounds, a quarter of which is copper.

2) The second and third units are identical ADB L-829 CCRs. Model number CHF6604. These two units are stand-alone models with all side and top panels installed.
a. These are common units with easy parts availability, in use at airports around the US and world.
b. Input power is 240 volts AC, single phase. Output is 6.6 amps maximum with 3 steps of amperage output. Each unit is rated for 4kW (the smallest size)
c. Both of these units have an ACE2 monitor and control system mounted on the door, ready for network connection.
d. Both units were in use and operational at the time of their removal. No parts have been removed.
e. These CCRs weigh 467 pounds each.
