DSS Digitally Controlled Ferroresonant Industrial Inverter Single Phase 3-50 kVA The DSS Inverter from AMETEK Solidstate Controls combines the best of both worlds – • The reliability and robust design of a Ferroresonant Inverter • The digital control and communications typically found only in PWM products.  he DSS is a true on-line, Inverter system  T that provides continuous, clean, regulated power for critical AC loads. Designed  specifically for process control and harsh industrial applications, the DSS combinesdigital control for enhanced communications, monitoring, control and  diagnostics capabilities with proven ferroresonant transformer design. T  he DSS also includes the LCD panel and user-friendly touch screen display found in our Digital Process Power systems for the ultimate in user control. Benefits of the DSS: • AMETEK SCI’s ferroresonant design (over 50 years of proven reliability) • High MTBF - exceeds 205,000 hours (23 Years) • Industrial grade - built to operate in extreme environments • Vacuum pressure impregnated (VPI) magnetics with 200ºC epoxy insulation (Class N)  • Long life LED indicators, front panel accessibility  • Unique crest factor circuitry provides full capacity for non-linear loads • All components are front accessible-no side or back clearance required  Integral system event recording for diagnostics (logs last 500 events)  - Lighted Mimic Panel Display • Microprocessor based alarms The Power Behind the Process Keypad Controls and Switches PROCESSPOWER INVERTER LCD and Touch Screen User Panel Inverter to Load w/Light Bypass to Load w/Light Static Switch Reset Retransfer Latching Alarm Reset Audible Alarm Silence Display On Inverter Enable (On/Off) Switch *Standard LED Indicators: Inverter Normal and Inverter Trouble Standard Mimic Screen (LCD Panel) Indicators Inverter Status (OK/Fail) Synchronism Status (In/Out of Sync) Static Switch Position (Inverter or Bypass) Manual Bypass Position (Inverter or Bypass) Bypass Status (OK/Fail) Shown with optional indicator lights

To “build” a model number, use the “code” in the matrix shown above, following the example format: DSS020-EE-FF-GG; where EE=DC bus voltage; FF=AC Output Voltage; GG=System Frequency. For Example: A 20 kVA with 120 VDC bus voltage; 120 VAC output, 60 Hz frequency; would have the following model number: DSS020-12-12-60. For 120/240 VAC output units, add “2” before DSE model number For custom systems, and for units which do not have a configurable model number, insert a ‘C’ in the model number as follows: DSS020C Specifications are subject to change. Top mounted cooling fans require 13mm (0.5 in) additional height. Certain optional features and/or combinations may require larger cabinets. For serious inquiries, please contact factory.
