Create A New AccountThe PS301 is the perfect combination of analog/linear working in conjunction with digital circuitry. Its linear supply section with a toroidal transformer paired with linear regulators nearly eliminate all stray radiation. The PS301 works well with other sensitive lighting and audio gear nearby. Its built-in microprocessor monitors temperature, voltage, and the current status of both the input and output. At 24 volts DC, power is thoroughly regulated and automatically decreases when needed. Current limiting in addition to short-circuit protection prevent hardware damage if a connection error or cable failure were to occur. A discreet built-in fan turns on when needed to decrease the overall temperature of the unit. The PS301 also features a program input that can be channeled to any or even all of its three circuits. The unit also functions in either the 120VAC or 240VAC range.

Our full policy is in our Terms and Conditions page.Please Note: Due to unprecedented raw material and component shortages for finished goods throughout our industry, lead times for items that aren't currently in stock are longer than normal and cannot be guaranteed at present. Equipment needed by a firm date must be noted at time of order. While VLS cannot guarantee delivery by those dates, we will work with our suppliers to do everything possible to meet deadlines. We apologize for the inconvenience and appreciate your patience.
Online orders received by noon Eastern time typically ship the same day. If your delivery due date is critical please note your due date in the order messages at checkout, and then contact us.
Why Noon? Well, while we stock quite a few items in our warehouse, many items we have dropshipped by our vendors. They need time to process the order, so to ensure that we can get the order to the vendor and give them enough time to ship it out the same day, we need to get the order to them as early as possible in the day.
Please also note that the shipping rates for many items we sell are weight and dimension based, as this is the method that FedEx and UPS use to rate the package's cost to ship.
We understand things happen and items occasionally need to be returned. To make things as hassle-free as possible, we have dedicated pages about our Returns Policy (what’s eligible to be returned) and our Return Process (how to go about returning eligible items)
