Designed to alternate power from one side of the cart to the other

The Ergotron LTSC30-TIMER is a timer module designed to alternate power from one side of the cart to the other to protect your circuit. It is used for LT charging cart (30 unit model). Charging 30 laptop computers at one time combined with the power demands of existing laptop battery technology can overload a typical 15 amp circuit. Anthro’s 30 Unit laptop storage cart is equipped with a built-in timing device that automatically switches the AC power supply from one side of the Cart to the other.

How it works:
When the Cart’s external control switch is set to internal power (to charge the laptops), the timer module will provide power to the Primary Panel (the side of the cart with the power cord) for the amount of time indicated on the Timer Adjustment (shown right). When that time expires, the cart will provide power to the Secondary Panel (the other side of the cart) until the time expires. The cart will continue to alternate sides until the external control switch is changed or the cart is unplugged. Every time power is turned off and then restored to the cart, power goes to the Primary Panel first. An indicator light on the Control Module (located on the bottom shelf inside the cart) indicates which side of the cart is being charged.

The timer is factory-set on a 25-minute cycle. Laptops and equipment with fully depleted batteries will require more than one cycle to fully charge. When the cart's external control switch is set to external power, the cart provides power to the two external receptacles located above the power cord.
