12
Volt DC Analog Time Switch
This 12 volt time control switch has a very accurate quartz clock
movement with 200 hour internal power reserve, so it keeps time even
if it is disconnected from the battery or the battery gets low. It
uses 10 mA to operate and can switch to up to 20 amps. Single pole
double throw contacts can turn one thing on while turning another
off. The timer has 3 on-off operations per day. Order extra trippers
for more on/offs per day. Minimum on or off time is 15 minutes. It
can be used to start and stop generators with proper generator control
circuitry. This is a dry-contact unit. Relay requires separate power
to operate. |

Voltage & Current
Controlled Relays
| Relays
are electromagnetic switches that can turn on or off a large amount
of current by using a relatively small amount of current. They contain
a coil that produces a magnetic field when a small current is applied.
This magnetic field pulls a metal switch to close the 'Normally Open'
contacts of the relay. When the coil current stops, the spring loaded
switch returns to the 'Normally Closed' position. The coil voltage
rating of a relay is the nominal voltage that must be applied to the
coil to cause the contacts to close. |
Voltage
Controlled Switches
These 12 or 24 volt, user-adjustable, voltage-activated, SPDT relays
have 30 amp contacts and come in active high (coil powered when voltage
rises) or active low (coil powered when voltage drops). Can be connected
either normally open (NO) or normally closed (NC). An active high
relay can be used as a low cost 30A PV regulator, a DC pump controller,
a diversion load control or to operate a large relay for a high powered
charge control. This active low relay can be used as a load disconnect
to prevent over-discharge of batteries. Voltage settings are user-adjustable
and can be read with a voltmeter. These relays consume 17mA when off.
Max current 30A at 12/24VDC, 3A at 48VDC. Measures 3x5.3x1.75 without
enclosure and 5x7x2 with enclosure. |

Amp DPDT Relays
These double-pole, double-throw relays can be used for up to 30 amps
at 12 or 24 volts DC or 250 volts AC. All contact surfaces are silver
alloy with gold flashing. Contact terminals are #8-32 screws and coil
terminals are #6-32 screws. Relays with 120 VAC or 240 VAC coils can
be used to build simple transfer switches. Relays with DC coils can
be used for remote operation of pumps and fans. By connecting a relay
with a DC coil to a voltage controlled switch, AC loads may be turned
on or off based on battery voltage levels. |

AC Transfer Switches
& Generator Control
Inverter
Bypass Switch
Wired between your inverter, generator and load center, this unit
allows you to bypass the inverter in the event of an inverter failure.
After the bypass switch is thrown, the inverter can be removed for
repair and the generator is connected directly to the loadcenter.
This is designed for inverters with built-in transfer switches. Maximum
current is 60 amps. Dimensions: 13.5 x 6.25 x 3.5. All components
are UL Listed. |

Automatic
Transfer Switch
Safely connect an inverter and an AC generator to the same house wiring.
Switch can be used with inverters that do not have built-in transfer
switch capability. If the generator is not running, the inverter is
connected to the house wiring. When the generator is started, the
house wiring is automatically disconnected from the inverter and connected
to the generator. A time delay feature allows the generator to warm-up
before the transfer takes place. Use the 120 VAC unit for code installation
of Trace DR or SW inverters in an RV or boat where the neutral and
line terminals must be switched. 2 year warranty. |

Dual Battery Switches
Battery
Selection Switch
This high current switch is designed for battery switching in boats
but can be used in land-based units. It permits selection between
one of two batteries or the connection of both batteries in parallel.
The off position also acts as a battery disconnect. Many people
are using these to choose between two banks of batteries or between
a main battery and a back-up battery. The switch surface mounts with
a slot for wires to enter from the bottom. Wires connect to 5/16
brass bolts. Capacity is 250 amps continuous and 360 amps intermittent.
For use on 6, 12, 24 or 32 volt systems. UL listed for marine use. |

Dual
Battery Relay
This relay is designed to isolate a second battery in a vehicle. The
contact terminals are connected between the positive terminal of the
starting battery and the positive terminal of the second battery.
The negative terminals of both batteries are connected to the vehicle
chassis. One of the coil terminals is connected to chassis ground
and the other coil terminal is connected to the ignition switch or
fuse box. When the vehicle is running, both batteries are connected
together in parallel and being charged by the alternator. When the
ignition switch is off, the contacts are open, disconnecting the second
battery from the vehicle electrical system. 80 Amp maximum continous
current. 12 volt coil. |

DC
Receptacles and Plugs
In our search for an economical, NEC approved outlet to use for low
voltage systems, we have decided upon something that is readily available,
a 240 volt, 15 amp receptacle. Our choice of this configuration is
based on the assumption that PV-powered remote homes will not normally
have appliances that use 240 volts at 15 amps. If you have a large
power tool it will usually have a 240 volt 20 amp plug on it. The
receptacles are duplex (two outlets) and they fit standard wiring
boxes and standard duplex receptacle covers. |
