I) GENERAL INFORMATION
The PDS-100 provides emergency and public safety vehicle electronics installers with a convenient, efficient, safe and
dependable method for adding distribution, circuit protection, timer and power control to communication electronics and
electrical devices. Its compact size allows installation under consoles and in interior compartments (not intended for
installation in engine compartment). As a standalone power distribution system, there is no interference with the vehicles
factory installed wire harness; the PDS wires directly to the vehicle battery. Each of the 6 circuits are individually fused
(ATO /ATC type) and wired to power-on/fuse fail indicator LED’s which simplifies circuit troubleshooting.
The 6 distribution circuits are configured into 3 load groups of two, power control to each individually group is
programmable via 4 user selectable options:
• Always ON
• ON with Ignition, OFF with Ignition
• ON with Ignition, Timed OFF (adjustable time interval) with Ignition
• ON with Battery, OFF upon Low Voltage sense LVD (adjustable disconnect point) with 20 second delay
In addition, the unit contains a master Under Voltage sense circuit that de-activates the whole unit @ 10.5V to save the
vehicle battery from extreme discharge, and automatically reconnects when battery charge recovers. Contact factory for
custom Master Under Voltage Shutdown threshold.
A Hight Voltage Shutdown circuit is also built-in that de-activates the whole unit @ 16.0V protecting loads against damage
due to malfunctioning alternators.
System capacity can easily be expanded by wiring additional PDS in parallel (18 circuits maximum), see options below.
Optional Accessories
1) Parallel Bus Bar Kit allows up to three PDS-100s inputs to be paralleled for additional circuits. One kit required
for two PDS-100s, two kits for three PDS-100s. Order model PBK, part number 390-5723-0.
2) Parallel Load Terminal Kit allows two output circuits in the same Load Group to be paralled for loads that exceed the
single circuit, 20 amp capacity, providing up to a 32 amp circuit. One kit includes one fork terminal with hardware
to allow one heavy cable to land on to two +12V load terminals of the same Load Group. Load ground cable connects
to single #6 screw located on the Battery Ground bar. Order model PTK, part number 390-5725-0.
II) IMPORTANT SAFETY INFORMATION
CAUTION:
• Read and fully understand the installation/operation manual before making any wiring connections.
• To avoid reverse polarity confirm correct polarity before connecting cables to PDS-100.
Stud ends are color coded with polarity:
RED = +12 VDC/Positive
BLACK = - 12 VDC/Negative
• Install fuse/circuit breaker on +12 VDC power feed/input wire to PDS-100. Size to match your loads and wire size.
• Connect high current feeder cables to the provided ¼” studs only.
• Run separate, dedicated ground cable (- 12 VDC) to PDS-100 ground stud. Do not rely on chassis frame
for grounding connections.
• 20 Amp maximum fuse. Use ATC/ATO style fuses only.
• 12 VDC nominal negative ground systems only
• Do not exceed 100 Amps total load per unit
• Replace protective cover after installation
