Prostar Controllers
USING ADVANCED
TECHNOLOGY FOR HIGH RELIABILITY, LOW COST PWM
BATTERY CHARGING SUPERIOR SERIES
SWITCHING
Designed by experienced PV
system engineers, ProStar's series design provides many advantages
compared to shunt controllers. Series regulations reduces FET heating
and lowers voltage stress on the power FETs. A
 series
configuration also improves protection against lightning surges and
reduces switching noise. The series design improves charging accuracy.
In PWM, series switching becomes self-correcting for temperature and
system voltage drops.
PS models 12, 20 and 30A are as listed above. MC models include
conformal coating, digital meter and ‘on/off’ switch. Digital meter
displays battery voltage, PV current and load current.
Notes: All models are the same size and weight:
6.0. in x 4.14 in x 2.17 in (15.02cm x10.5cm x 5.5cm)
0.03 cu.ft./ 1.0 lb (0.001 cu.m. / 0.45kg)
New Standard Features (April 2000): PV short circuit
protection, field adjustable ‘DIP’ switch for battery type voltage
regulation and LVD settings and optional remote battery temperature
sensing cable connection.
FEATURES
- Automatic voltage
select. Provides flexibility for either 12V or 24V systems,
Processor automatically configures for correct system voltage.
- Prevents reverse
current. Series switching prevents battery from discharging ot
night through the array.
- Temperature
compensation. Corrected setpoints referenced to ambient
temperature
- Field selectable.
Electronic selection of either a sealed or flooded battery. Two
sets of optimized controls parameters are built into the processor
- PWM battery charging.
Series PWM design will reduce heating and system voltage drops.
Precise finishing charge under all system conditions
- Reverse polarity
protected. Full electronic protection against any sequence of
reversed wire connection
- Battery sense.
Eliminates voltage drops for more accurate control. Automatic
default to battery connections if sense is not connected
- Low voltage disconnect.
Low resistance FET's will handle load starting currents up to 10
times rating. Electronic short-circuit protections. LVD is current
compensated with no parasitic loss
- Mannual disconnect.
(Option) Button will instantly disconnect all PV and load
connections. Same button serves as a mannual disconnect
- Battery charge LED's.
Three LED's indicate relativebattery state-of-charge. All LED's
are pulsed to minimize parasitic loads
- LCD meter.
Three-digit display with reflective foil for easy readability.
Wide temperature range from -30 to +85 deg C. Values displayed are
accurate by 1 - 2%
