Our Latest STO-P UPS series
We've added a high power UPS STO-P to our expanding line of STO-P Power Fault Protectors. The new STO-P UPS40xx series is capable of handling up to 40 amps continuously and is fitted with an internal backup battery that eliminates undervoltage conditions caused by engine cranking, brownout or blackout. It's extremely rugged, housed in a diecast aluminum case sealed to IP65 standards and rated over a -40C to +85C temperature range. It has all the standard 'time domain' suppression features that have made STO-P so popular in the past.

STO-P's ' Time Domain ' Approach

STO-P works in the 'time domain' and applies different techniques to 'trap', 'block', 'dissipate' or 'fill' (TBDF), or otherwise remove, each event as it occurs. For example, a fast rising high voltage transient usually occurs just prior to a charging system failure. But, a few hundred microseconds later an extreme Overvoltage condition follows. The first event is detected and suppressed by STO-P, but as the fault continues and transforms into a dangerous overvoltage condition, other 'trap', 'block', 'dissipate' or 'fill' (TBDF) methods are successively used to protect the equipment. 

We divide Fault Events into time domains:

  • DOMAIN 0: 1 nanosecond to 1 microsecond
  • DOMAIN 1: 1 us to 1 millisecond
  • DOMAIN 2: 1 ms to 15 ms
  • DOMAIN 3: 15 ms to 1 second
  • DOMAIN 4: over 1 second

Then, depending on the 'fault characteristics' detected, we use different TDBF techniques to remove or suppress the fault. This broad spectrum Time-Domain approach allows us to achieve maximum possible suppression of fault conditions. The downside is that it costs more than the 'standard' ineffective methods, but that cost is spread over the entire bank of electronics carried on the vehicle or vessel. So overall it is extremely cost effective to install, and yields great savings in maintenance and repair costs.

U.P.S.- RESERVE POWER

Computer users are familiar with the problems of 'brownout' when AC Main voltages dip to a level where memory is corrupted. The same undervoltage effect occurs in 12/24/28 volt d.c. powered systems. The momentary starting of an engine, or the sudden increase in load due to some other equipment can cause small voltage dips that can destroy the memory on a GPS or onboard computer system. STO-P is 'UPS Enabled' - when voltage levels dip, the backup battery will automatically supply power (up to 45 amps!) to your equipment.

The Bottom Line!

Downtime due to premature failures, and costly service calls are eliminated. For the Vendor, it means better Client relationships and far less frustration for field technicians! For the 'End-User', it means years of reliable equipment operation, free from 'bugs' and 'glitches'.

If you need a clean source of power - STO-P will meet or exceed your expectations.
