TECHNICAL DESCRIPTION
All L&L kilns that use the DynaTrol electronic control typically get their control voltage transformed from the incoming line voltage that the kiln operates on. This is standard and proper industrial practice. However, in some cases this is not desirable. If you have problems with short power outages, voltage spikes, voltage drops, or excessive environmental line noise (such as is caused by 3 phase motors or phase angle fired SCRs), this can cause unpredictable havoc with the control. These are conditions found on overburdened power grids, in some factories and sometimes in rural areas. It is hard to detect without very specialized equipment (most electricians would not be able to “see” these problems).
In such cases we recommend having the control feed by a separate 120 volt line (with a standard 6 foot long cord) and having that voltage filtered though an EMI (Electrical Magnetic Interferance) noise filter. We then recommend plugging the 120 volt cord into a good computer surge protector or better yet a UPS (Uniteruptable Power Supply) power supply with isolation transformer. You can buy a good UPS for at a computer store for less than $100.
PRICES
This is an option available from our factory for a cost of $225.
We can retrofit older panels for the same charge (customer must pay for shipping both ways).
