ROSS ENGINEERING CORPORATION
A key feature of our rotary switches is their simple mechanical design which results in conservative stress levels for trouble-free, long life use. In addition, each rotary switch has a reinforced chassis design utilizing G-10 or G-11 fire retardant anti-tracking coated epoxy glass insulation. G-7 silicone glass is used for special applications where RF or high temperatures are involved. Heavy duty contacts, specifically designed to minimize corona in the Ross rotaries, are made of highly conductive yet weld resistant alloy with high contact closing force. This high force gives our rotary switches high momentary current capability and a reputation for their ability to withstand high shock and vibration as well as other severe environmental conditions. Ratings to 150kV, to 200A. When immersed in insulating oil, fluid or gas, the voltage withstand value is at least doubled and the interrupt capability is much greater. In a gas atmosphere, no modification is required. However, immersion in oil or fluid may require modification in some cases, at an extra cost (optional). Each unit is either manually or electrically operated. One SPDT contact is standard on most units. The auxiliary contact is used as an interlock for protection against "Switching Hot".

Fast - All operator controls are located on the front panel to expedite testing. The entire test can be performed in a matter of seconds! Pays for itself in time and stress savings. Versatile - Measures Leakage Current in accordance with UL, CSA, EN, and IEC/ International Standards. Includes ability to perform open neutral, open ground, and line polarity forward/reverse test conditions. Adaptable - Universal rear panel receptacle allows for testing products with any plug configuration. Accurate - True RMS meter accurately measures both sinusoidal and non-sinusoidal waveshapes. This is important when testing products using a switch mode power supply which can generate non-sinusoidal leakage currents. Calibrated, traceable to NIST. Flexible - A front panel switch permits testing either through the power cord of the product under test, from surface/ patient connection-to-ground, or from surface/ patient connection-to-surface/ patient connection. Portable - Lightweight, with integral handle. Other Features - Product Ground Switching (grounding conductor maintained to device under test when not measuring leakage). Automatic front receptacle disconnect when configured in the 240V test mode (prevents inadvertent connection of 120V when configured for 240V operation). Proven - These are the only leakage current testers designed and supported by Product Safety experts. That is part of the reason why they have become the standard in the industry. Full technical support by experienced safety engineers.
