DOLI Power Amplifiers Digital Power Amplifiers . . . . . . always the fitting amplifier for your instrument drive!
Power amplifiers with 12W, 160W, 320W, 1,100W and 2,500W either EDC-internal or as external desk top unit! Electronics for testers
DOLI Power Amplifiers
DOLI offers electronics and very powerful software for data acquisition and closed loop control for testing instruments like tensile testers.
DOLI offers different amplifiers for DC-motors and servo valves. AC-motors and other drives are controlled by a ±10V output.
The software runs on the DOLI hardware platforms as EDC220V, EDC222V and EDC580V and others. It is configurable within a wide range to satisfy all tasks of a testing instrument. The communication between DOLIs EDC-system and the PC happens via USB or Ethernet. DOLI uses a safe protocol called DPX on this serial line to transmit commands and data in both directions.
DOLIs internal digital power amplifiers can be implemented into the desk top units EDC222V and EDC580V. They are available for DC-motors with 12W, 160W and 320W. The power amplifiers DC1100 and DC2500 are external designs for DC-motors with 1.100W respectively 2.500W. They are available for all three external digital controllers, i.e. for the built-in unit EDC220V, as well as for the desk top units EDC222V and EDC580V.
• High control accuracy: ±1 increment of the transducer • No drift and therefore no brake needed • No tacho needed • Extremely high dynamics of the drive • Direct connection to the EDC-systems • Safety low voltage PELV from IEC 204-1 guaranteed • CE conformal • Cost effective

DOLI Power Amplifiers The external power amplifiers DC1100 and DC2500 External DOLI power amplifiers are available for DC-motors with 1.100W (DC1100) and with 2.500W (DC2500). They offer a digital interface to the EDC. A negative feeder possibility of 50W (DC1100) or 200W (DC2500) enables cyclic tests, e.g. spring tests. The power amplifiers contain the complete contactor and relay technics needed for a safe turn-off in case of emergency stop, softends etc. A function check of the safety relevant elements is guaranteed in connection with the controller componentries. The DC1100 and the DC2500 power amplifiers do not need a tachogenerator at the DC-motor, as they are controlled by an incremental transducer on the motor shaft.

EDC220V/222V/580V Full stand alone systems for all types of material testing instruments. Excitation and A/D-conversion of transducers as well as complete digital control of the connected drive are included. Load resolutions and options: EDC220V/222V: ±180,000 Steps (two option slots) EDC580V: ±180,000 Steps with 4ETF or 4FAD (seven option slots) DOLI produces electronics for testing instruments since 1979. The first digital contoller was presented in 1984. 95% of the production is delivered to producers of instruments worldwide. DOLI supplies electronics, motors, amplifiers, application software and has enough know-how to support producers in the field of new testing equipment and retrofits.
