Innovative high-voltage supply modules for air pollution preventers with small and large electrostatic filters
REMO-HSE exhibits at „electronica 2010“ – Stand A2.239Rattiszell, )
High-voltage supply modules of the MSR Series from REMO-HSE are robust, compact and designed for smaller electrostatic filters. The MSR Series comprises four units with an output power of 30 W, 60 W, 90 W or 120 W; the nominal output voltage, with either positive or negative polarity, can be set between 5 kV and 30 kV. Both output voltage and output current can be set to any value between 0% and 100% of the related nominal value, depending on the design either by a simple potentiometer or via an analogue interface. Optionally, all modules are also available with a second high-voltage output for the collector.
Additional features include soft-start and spark protection. Depending on the type, a potential-free relay contact for the “load” status information and two LEDs for displaying status information (over-temperature, constant voltage /constant current) are provided additionally.
Compared to the MSR Series, the modules of the MMR Series provide more connection and control features and cover a much wider voltage and power range. Currently available are designs with 60 W, 120 W and 400 W output power at a positive or negative output voltage of 5 kV to 120 kV. All units of the MMR Series are equipped with a wide-range power supply with PFC and provide soft-start as well as spark detection with spark counter. A particular advantage of this series is that the modules can be connected in parallel for higher output power. Three LEDs as well as two potential-free relay contacts provide status information about the high-voltage, the load and the temperature. In addition to adjusting the output voltage and output current, the modules of the MMR Series also allow for adjusting the current-/voltage characteristics (e.g. soft response). Depending on the design, these settings are either performed via a potentiometer and/or an analogue input. An optional communication module provides interfaces to the most common PLC and industrial bus communication standards.
All modules of both series are short-circuit proof against ground, automatically switch off at over-temperature and are protected against overvoltage and over-current by a self-acting transition between constant voltage and constant current regulation.
