2. PRODUCT DESCRIPTION
2.1 SYSTEM OVERVIEW
The DynAmp, LLC LKP Series 4 Channel OEM is a system for accurately measuring direct
current in a bus. Each model of the LKP Series 4 Channel OEM consists of a two-piece
Measuring Head, a Metering Unit, and one or two multi-conductor cable depending on the
model.
2.2 ADDITIONAL MEASURING HEAD DETAIL
A magnetic core encircles the bus passing through the center of the Measuring Head.
Magnetic null detectors are mounted in air gaps around the core. Each null detector is flanked
by coils located on the magnetic core.
The housing material for the LKP-6 and LKP-12 models is a tough plastic with a fiberglass fill.
The larger LKP-15, LKP-30 Measuring Heads are constructed of cast aluminum with a tough
epoxy finish, insulation from the bus being provided by a 3/8 in.(9.5 mm) layer of high grade
epoxy. The Measuring Head halves are easily joined around the bus by use of 8 bolts.
Electrical connections for LKP-15, LKP-30 models are made through two multi-conductor
cables connected to each half of the Measuring Head. On LKP-6 and LKP-12 models,
individual conductors from each half of the Measuring Head are brought out to an external
terminal block, which in turn is connected to the Metering Unit via a single cable. All wires from
the Measuring Head are color coded and clearly marked according to the interconnection
diagrams supplied with this manual.
2.3 ADDITIONAL METERING UNIT DETAIL
The solid-state components of the Metering Unit are mounted on a heavy aluminum base plate
and are protected by an aluminum cover. The enclosure has a rating of IP20, with an available
IP54 enclosure option. Electrical connections from the control board and power board are
brought out to a terminal block which serves as a tie point for the Measuring Head cable, output
circuit, and ac input power. The Metering Unit provides output terminals that can provide the
customer a voltage signal proportional to the measured current and/or a current output.
2.4 INTERCONNECTION CABLE DETAIL
A standard 33-foot (10 meter) interconnecting cable is supplied with each system (longer cable
lengths are available - consult the factory for details). Each of the individual conductors is
tagged with a numbered label corresponding to a terminal block connection, providing an easy,
hookup.
