Cabinet/Enclosure Design
There are no limitations on the design of the enclosure for the tester, and each tester is individually designed for the specific needs of the customer. The standard enclosure is fabricated from extremely durable polypropylene, but other materials and constructions are available if desired.

Each tester is professionally designed in the SolidWorks 3D modeling system, which provides a virtual real-world view of the entire system. Special care and attention is given to the usability of the tester, which is based on actual experience working with the same types of connectors and cables that you use for your PD system. For example, connectors that are more difficult to handle by the operating technician are placed farther apart and at optimal waist level, with emphasis on making the task easier for the technician to perform.

The enclosure can be designed for in-house benchtop use, or for portable field use. Generally speaking, the size of the enclosure is dictated only by the number of connectors required. Before a tester is constructed, the enclosure design is reviewed with the customer to ensure that it meets the customer's needs.
SolidWorks Model
RTS Engineering stands behind every tester shipped, and that goes above and beyond just design integrity or even warranty issues. The design and construction of the PD Tester is not just skin deep. Each tester contains two industrial computer systems and redundant self-protection circuitry to isolate the computers from all aspects of operator error. As-built photographs of every tester are retained for the life of the tester, should one ever require service due to abuse or operator error (whether covered by warranty or not).

One such case (and the only case of a required repair to a tester) involved the accidental penetration of the enclosure by a forklift operator. The customer opted for a "self-repair remedy" using factory supplied instructions and components. Within 24 hours of the damage, a detailed repair manual was written, including complete photographic-based instructions from the as-built photographs of the tester, describing how to replace the user-damaged components. (Even though the forklift destroyed one of the two computers, there was no charge to the customer beyond the actual replacement cost of the parts, and no charge was made for the specialty repair manual. That tester is still in active service today.)

The image below shows one of the Load-Banking model testers, which is the most complex of tester systems. This version of tester uses double-redundant protection circuitry, because even though it needs to protect itself from unexpected power, it must also protect the operator from unexpected power too.
