Solid State DC Relay 10A
1 of 2
SOLID STATE DC RELAY

This is a solid state DC relay for switching DC currents of up to 10 amperes at voltages from 5vdc to 220vdc.  A small red light indicates when it is on. 

These work like mechanical relays but without the contact life issues.  Control voltage from 3-32vdc causes it to connect the two terminals.  This control voltage draws less than 25 ma.  You could actually use a bare Arduino digital output to switch up to 10 amps at up to 220vdc voltage.


Load Current: 10A peak.  Limit to 5 amperes continuous load.
Load Voltage: 5-220V DC Actual (24-220V DC MArked)
Control Voltage: 3-32V DC
Control Current: 5-25mA DC

Price: $14.95

Solid State DC Relay

SOLID STATE DC RELAY

This is a solid state DC relay for switching DC currents of up to 80 amperes at voltages from 5vdc to 220vdc.  A small red light indicates when it is on. 

These work like mechanical relays but without the contact life issues.  Control voltage from 3-32vdc causes it to connect the two terminals.  This control voltage draws less than 25 ma.  You could actually use a bare Arduino or Macchina output to switch voltage.

We use these to switch DC voltages to heating elements in place of a Tyco Kilovac contactor.  Used with the JLD612 temperature controller, there is really no life limit to the number of cycles using this device, nor contact wear from breaking currrent flows repeatedly.

Load Current: 80A peak.  Limit to 40 amperes contuous load.
Load Voltage: 5-220V DC Actual (24-220V DC MArked)
Control Voltage: 3-32V DC
Control Current: 5-25mA DC

12v Battery Disconnect
1 of 2
ProMax 12-Volt Heavy Duty PriorityStart! Automobile Battery Protector / Electronic Cut Off Switch

Heavy Duty Battery Disconnect Switch
-- Maintenance Free & Ecologically Friendly
 -- Totally Automatic Computerized Voltage Disconnect System
 -- Automatic Battery Reconnect that's Convenient & Safe
-- Easy to Attach in just 3 Simple Connections
-- Maximizes Battery Life, Preventing Electrical Damage
-- Disconnect Threshold is Factory Set at 11.7V for 12V Systems
-- Handles 1,000 Starting Amps
-- Designed for an Under-Hood Environment
-- Engine Run & Hazard Light Protection
 -- Universal Design fits both Top & Side-Post Batteries
 -- For Surge Protection / Fully Automatic Engine Starting Protection for your Car, Boat, or other Vehicle
-- Operates only when Accidental Deep Discharge of Vehicle [Auto] or Marine Batteries are Taking Place
-- To Operate Headlight Switch, Step on Brake Pedal, or any other Electrical Accessory, and it will Automatically Reconnect
-- Unit can only be used with Class 1 - 6 Vehicles with a Maximum of 1,000 Peak Starting Amps (Rated at 250 Continuous Amps)
-- Monitors Battery Voltage & Automatically Disconnects any Undesired Drain on your Battery as the Voltage Reduces (when Engine is not running)

How It Works: . PriorityStart! is an automatic heavy duty computerized on/off switching system, protecting battery voltage and starting power. If battery voltage drains below 11.7 volts when engine is off, it automatically disconnects the load. The battery voltage immediately recovers. . TO START: Just step on the brake pedal, and the starting power is automatically reconnected. It is designed to handle 1,000 Starting Amps. (PriorityStart! is not a battery charger or booster that is used after the battery has already been damaged.) Installation: .

PriorityStart! attaches easily to any 12 Volt top or side-post vehicle battery. No modifications are necessary. Three Easy Connections: 1. Connect existing vehicle positive cable to PriorityStart! 2. Connect PriorityStart! cable to battery positive post. 3. Attach ground wire to battery negative post. .

Maintenance Switch
BLUE SEA SYSTEMS MAINTENANCE SWITCH

Slightly smaller than our GUEST maintenance switch, these are stil pretty hardy switches with impressive current handling capabilities and able to mount in smaller spaces.  Blue Sea claims 2700 amps for up to 10 seconds and 600A continuous.  Use this switch to split your pack and set to OFF when working on your car to avoid shocks.  

Also used to turn off car when parking for days or weeks without charging, this will prevent the gradual drain of your pack from parasitic small loads such stereo, clock, speedometer, and instruments.

Emergency E Stop Pushbutton
1 of 3
Our highest quality emergency disconnect slap switch.  

This Cutler Hamner swithc features both Normally Open (NO) and Normally Closed (NC) connections and has a ruby 12v light in the center of the switch with clear EMERGENCY STOP imprint on the switch head.

The switch is engaged by pushing it in - a very solid and satisfying THUNK when activated.  It just feels solid. With both NC and NO connections, it can either activate or deactivate an external 12v circuit to make or break a pack using an external contactor.
 
This switch is NOT for use in switching high voltage but normally used to switch 12v to a contactor to disconnect the pack.

Rugged industrial build with his very high quality emergency disconnect switch.

 It features a push pull design not  a "twist lock"  and chrome plated thread shaft and lock nut for  in-dash installation. If you are looking for something that will add some eye candy to your build -this no-nonsense EMERGENCY STOP swithc is your must-have product.  BLING for your THING
