SERIES 1000 CosaTron Custom System
Model 1100 Power Generator, Electrodes and Support Frames (tracks)
Power Generator
Each Power Generator shall produce High (HV) direct current and High Frequency (HF) alternating current. The HV/HF output
of one generator is sufficient to handle a plenum cross section of 60 ft² maximum. More than one generator is required on
plenums that exceed 60 ft² . When more than one generator is used on a plenum, wiring must be done in accordance with
manufacturers wiring diagrams and instructions to ensure generators do not back feed each other through the electrodes.
The HV output is 25 kvDC at less than 10 microamps and is connected to the smaller HV electrode with a factory supplied red
wire. The HF output is 500-600 VAC at less than 350 microamps and is connected to the larger electrode with a factory
supplied black wire. The manufacturer shall provide a prefabricated cable kit and wiring diagram for connecting the power
generator to the electrodes, maximum wire length 10’. The cable kit shall be installed in one continuous length without splices.
If the power generator is mounted outside of the plenum, the two wires shall be run in a single conduit, supplied by the
installing contractor. If the generator is not mounted on the plenum housing the electrodes, a ground wire shall run from the
generator to the electrode support frame in the same conduit. The power generator does not have a weatherproof enclosure. If
2
the unit is installed outdoors in the elements, the power generator must be mounted inside the air unit in an area that will allow
ventilation for cooling and allow proper access for cooling and service.
Electrical requirements are 120v/1/50/60Hz, or 220v/1/50/60Hz 2-amp circuit wired through the plenum safety door switch.
This will interrupt power to the power generator when an access door is opened, per the manufacturer’s wiring diagram and
instructions. Maximum current usage is 50 watts per power generator. All line voltage shall be done in accordance with all
local and national electrical codes.
Electrode Assemblies and Support Frames (Tracks)
Each Electrode assembly shall consist of a smaller HV electrode and a larger HF electrode element separated by 3”
insulators. When the same generator powers 2 or more electrode assemblies, they are interconnected with special connector
straps to maintain proper spacing and electrical continuity, per the manufacturer’s submittal drawings and instructions. The
electrode assemblies are mounted in special support tracks in the air unit or factory supplied plenum section, perpendicular to
the airflow immediately down stream from the filters, before the cooling coil.
The electrodes shall not be installed in an area of the plenum that has insulation exposed. If necessary a grounded solid
sleeve or perforated liner, 9” in width and in direction of airflow shall be installed around the electrode assemblies. The air
passing through the HV electrode and then the HF electrode shall not exceed 650 FPM face velocity, for optimum
performance the air entering the electrode should not be lower than 60 degree FDB & 53 degree FWB or 60% RH. The
minimum clearance for the HF electrode shall not be less than ¾ of an inch from any grounded object or material. The
minimum clearance for the HV electrode shall not be less than 3” from any grounded object or material inclusive of filter media
and media support ties. The static pressure loss through the electrodes is less than 0.05” WG at 650-FPM air velocity. (The
electrode assemblies shall be constructed so they have no corona or corona produced ozone.)
Accessories
PLENUM ACCESS SAFETY DOOR SWITCH
One switch shall be installed at each access door to the electrodes and shall be wired into the 110/120 VAC line voltage circuit
to interrupt the power to the power generator(s) when any access door is opened. The switch shall be an enclosed, carry over
snap action type, SPST, N.O., with minimum 5.0 amps per power unit, 125/250 VAC rating, UL listed. Switch shall be
arranged so it is impossible to be locked “ON” when the access door is open. All switch hardware accessories shall be either
zinc or cadmium plated.
OPTIONAL EQUIPMENT
REMOTE INDICATOR LAMP UNIT RM-150 (HF and HV)
Each power generator shall be equipped with one Model RM-150 to monitor that the power generator HV and HF output is
operational and the Dwyer differential pressure switch is sensing pressure at the filters at any remote location. The
manufacturer will supply the proper accessory plug to mate to the power generator. The installing contractor shall furnish the
appropriate cable to handle the HV/HF 24 VDC output and the Dwyer pressure switch 110/120 VAC circuit for interconnection
between the power generator and the RM-150 remote indicator lamp unit. Installation procedures and materials used shall be
in accordance with the manufacturer’s instructions and wiring diagrams. Any and all connections shall be done in accordance
with all local and national electrical codes.
REMOTE COUPLER UNIT – RCU-230
Each unit shall be equipped with one RCU-230 remote coupler unit to provide interface that the HV/HF output is operational on
a building management system. Installation procedures and materials used
shall be in accordance with the manufacturer’s instructions and wiring diagrams. The installing contractor shall provide the
appropriate 2 or 3 conductor wire between the RCU-230 and the remote read out panel. Any and all connections shall be
done in accordance with all local and national electrical codes.
Model ES-5200, ELECTRODE SENSOR UNIT

This data is then converted to a low voltage analogue signal for connection to a remote wall indicator panel or a hand held
digital readout meter showing the actual voltages and frequency of the electrode elements. It can also be connected to most
building monitor systems capable of receiving and or accepting 0-2 or 0-5 volt analogue signals.
There is one electrode sensor/receiver unit mounted on the air handler unit or plenum section for each power generator in the
system. The unit enclosure is anodized aluminium and can be mounted on a surface 4” x 9” with the faceplate projecting 3” off
the mounting surface. One long side of the unit requires access for AC input power and connection to the remote wall
mounted indicator panel or handheld digital readout meter.

The unit is attached to the last electrode in a series with a prefabricated cable kit, supplied by the manufacturer. This cable
should be installed in one continuous length without splices to a maximum wire length of 10’. The red HV wire is attached to
the smaller HV electrode and the black HF wire is attached to the larger HF electrode. This is not a waterproof enclosure. If
the air handler is installed outdoors in the elements, the electrode sensor unit must be mounted inside of the air unit to allow
for easy access for service personnel.
Electrical requirements are 110/120 VAC, 1 Phase, 60 Hz, 1 amp circuit. Maximum current usage is 30 watts for each
electrode sensor unit. All mechanical and electrical procedures and material shall be in accordance with the manufacturers
written instructions and diagrams. All local and national electrical codes apply.

output from the electrodes is outside the recommended optimum operating range. The unit is attached to the last electrode in
a series with a prefabricated cable kit, supplied by the manufacturer. This cable should be installed in one continuous length
without splices to a maximum wire length of 10’. The red HV wire is attached to the smaller HV electrode and the black HF
wire is attached to the larger HF electrode. This is not a waterproof enclosure. If the air handler is installed outdoors in the
elements, the electrode sensor unit must be mounted inside of the air unit to allow for easy access for service personnel. The
ES 5270 has the added capacity of indicating a dirty filter condition when used in conjunction with the PE switch.
