Basic Operation

Solar Converters Inc. Voltage Controlled Switch is a simple power relay switch which has user adjustable voltage setpoints. Normally the relay is not powered, connecting the common terminal (C) to the normally closed (NC) terminal.

The Active High unit monitors the incoming voltage and if it goes over the "high" setpoint for 3 seconds, the power relay will switch on, connecting the common terminal (C) to the normally open (NO) terminal.

Once the relay is on, the unit monitors the incoming voltage and if it goes below the "low" voltage setpoint for 3 seconds, the unit will turn off the power relay, connecting the common (C) terminal to the normally closed (NC).

Active Low operation is identical to the Active High listed above BUT the relay operation is opposite.

In Active Low operation, the unit monitors the incoming voltage and if it goes below the "low" setpoint for 3 seconds, the power relay will switch on, connecting the common terminal (C) to the normally open (NO) terminal.

Once the relay is on, the unit monitors the incoming voltage and if it goes above the high voltage setpoint for 3 seconds, the unit will turn off the power relay, connecting the common (C) terminal to the normally closed (NC).

• Single unit 12, 18, 24, 36 and 48 V operation
• Easy to setup, setpoints have a 1/10 th. scale factor. To set 12 V, set the setpoint to 1.2V

Special Shipping Note:
All Solar Converter Products are behind in production. These items are usually shipped directly from the manufacturer in Canada. They cannot be shipped by any expedited methods such as UPS Blue or Red. They will generally be shipped via Canadian Express Mail which avoids import brokerage fees of $50-$60. Lead time on these products may be up to 4-6 weeks depending on their production. This is true of all Solar Converters products with the exception of the battery desulphator (item code SORBD-2) that we stock in our warehouse. If you want Solar Converters products to be shipped by normal Canadian Post, but would prefer to have the rest of your order to be shipped by a faster method, please write this information in your order's notes during checkout.
