Click onto image for a larger view.

1) Flexcharge Programmable Digital 12 volt d.c. timer and

load controller.

Each day can be programed with its own unique timing pattern and

eight on and eight off events can be programed independantly.

The timer operates on 12 volt d.c. and can control either

d.c. or a.c. loads.

It can handle an a.c. load up to 120 volts through the switching side

of the timer.

For use with a 24 volt d.c. or 48 volt d.c. Battery System please

click onto the following link: Flexcharge Timer Wiring

The internal battery maintains clock and memory for up to 3 months

without external power.

Consumes less than 3 ma in standby mode and 15 ma when the

switch turns on.

Runs up to an 8 amp inductive (motors or loads that surge) or a 16 amp

resistive (lighting or heat) load.

Also has manual on/off override.

Display and controls have a removeable plastic cover.

Easy to set up with the handy wire terminals on the bottom.

Simple to program.

Dimensions: 3-7/8" wide including mounting flanges, 3-7/8" high including

wire terminals and 1-7/8" front to back.

We have been using a Flexcharge timer for outdoor area lighting for years.

2 - A)

Timer switch (count-down timer) from Light It Technologies

for both 12 or 24 volt d.c.

This switch will work on either 12 or 24 volt d.c. - it automatically

senses the voltage you are using and outputs the incoming voltage.

It will operate a load up to 6 amps.

You can adjust the run time from approximately 55 seconds to

3-1/2 hours.

Once set, using the blue time adjustment wheel shown in the picture,

you just press the button.

The load will go on and run the set time - the led indicator light shows

that the unit is connected to power.

These are well suited for use in vans with lift gates and in service

vehicles.

It also has an extra pair of wires which allow you to remotely start the

count-down timer.

Due to the advanced microprocessor, the housing should be grounded

to bleed off any static charges.

Not to be exposed to rainfall nor moisture.

The housing is 2-1/16" long, 1-13/16 front to back and 1" tall.

The mounting plate is app. 3-1/4" long by 2" front to back and the spacing

of the two mounting holes is app. 2-15/16" center to center.

One year limited warranty by Light It Technologies.

Linear Current Boosters - FAQ

Solar Converters, Inc.

2) Linear Current Boosters for pumping applications:

A linear current booster allows a pump to run longer throughout

the day when connected directly to a photovoltaic module.

It will start earlier in the day and run later in the day than in a

module to pump only system.

When considering a linear current booster please make sure

that your modules are sized large enough to run your pump

properly.

These LCB's are designed to shut down the pump if the incoming

power is low enough to damage it.

There have been instances where the panels were undersized for the

pump and would just operate it when connected directly to the pump.

In a case such as this, the LCB will not let the pump run to prevent

damage to the pump.

The amperage ratings are the actual ratings after being derated

for long term use.

Custom output voltages can be special ordered.

We can special order higher voltages and current ratings,

please call us for pricing and availability.

Application Notes:

This Pump Power Tracker(TM) is quite capable of putting out over

25 amps into a stalled load even from a single 30 watt 4.5 amp panel.

It is recommended that a fuse or overtemperature switch matched to

your pump motor be incorporated in the system to protect your pump

or motor.

Float switch operation draws microamps of current, i.e. small wire gauge,

allowing long distance runs between float switches / holding tanks, and

PV / pump driver without the need to string long lines of heavy gauge wire.

Unit is a true 10 amp unit, all necessary derating already accounted for.

As with all electronics, it is recommended the unit not be mounted in direct

sunshine.

Solar panel or energy limited input only.

Voltage Controlled Switch

by Solar Converters, Inc.

These switches offer automatic ON or OFF control of loads (fans,

pumps, etc.) and can be set to a specific voltage.

They are available in "Active High" or "Active Low".

What this means is that the switch can be set so that it is

activated when a voltage goes up (active high) to a set point or

goes down (active low) to a set point.

The switch will either open or close, the green lug block shown in the bottom

of the picture has a common and as well as a normally closed and normally open

connection, when the voltage set point is reached.

An example: an active high switch with a fan connected will start the

fan when the voltage reaches a set point - many people use these to

ventilate battery boxes when the battery is being charged and the

voltage reaches the set point.

It can also be used to divert excess generated power to an auxillary

load.

The active high type is also widely used as a low voltage disconnect.

Operation:

When the d.c. voltage from the battery (d.c. power source) is at or above the high set point

the relay will be energized.

When the d.c. voltage from the battery (d.c. power source) is at or below the low set point

the relay will be de-energized.

__________

An example: an active low switch with a generator start or secondary

power source will close the circuit when the voltage drops to the set

point.

It can be used to signal an alarm as well as to operate a battery charger until the voltage

comes back up to the high set point.

Operation:

When the d.c. voltage from the battery (d.c. power source) is at or below the low set point

the relay will be energized.

When the d.c. voltage from the battery (d.c. power source) is at or above the high set point

the relay will be de-energized.

There is a three second delay when the voltage reaches the set point.

This helps to keep the switch from falsely activating during a momentary voltage

surge or dip.

Operates on 12, 18, 24, 36 or 48 volt systems (10 to 60 volts d.c.)

Very simple to set-up and use.

The internal relay with handle from 30 amps at 12 volt d.c. up to 8 amps at 48 volt d.c.

as well as up to 30 amps at 120 volts a.c.

Available in an open frame model (you supply the mounting box which

is available at most home centers) and a closed frame model which includes

the mounting box.

We stock these in the open frame configuration.

Closed frame models can be special ordered - it takes from 2 to 4

weeks for delivery from the factory.

Dimensions of the open frame model: 4.125" by 2.8" by 2" and weighs

app. five ounces.

The following information is for operating a Flexcharge programable

digital timer from a 24 volt d.c. or 48 volt d.c. battery bank.

You can tap off 12 volt d.c. from your 24 volt or 48 volt battery bank to

power up the timer side of the Flexcharge timer, the two wire lugs on

the left side.

Before doing this please call me so I can walk you

through it.

If more than 12 volt d.c. is connected to the timer

side the unit will be damaged and the warranty will

be voided.

As it uses app. 3 ma for the timing function and app. 15 ma. when it

switches your loads on, it should not cause a higher voltage battery

bank to "become out of balance."

You can connect your 24 or 48 volt d.c. power to the switch side of

the timer.

NEVER connect any voltage higher than 12 volt d.c. to the

two lugs on the left.

Please call us at (562) 423-4879.
