Safety according to IEC/EN 60950-, UL/CSA 60950-, IEC/EN 5078, IEC 600-, UL 508 9 7.6".9" Description The Convert Select front end series represents a family of DIN-rail mountable AC-DC and DC-DC converters with power factor correction. The converters have been designed according to the latest industry requirements and standards. They are ideal for use in outdoor and other demanding applications to power building control systems, factory automation, industrial controls, instrumentation, electromagnetic drives, fans, and other DC loads. Different models are available with a single output or two independently regulated, electrically isolated outputs with, 6, or 8 V. Special models for battery charging are available. Key features of the Convert Select line include power factor correction with low harmonic distortion, negligibly low inrush current, high immunity to transients and surges, and low electromagnetic emissions. Internal protection circuits such as input over- and undervoltage lockout, thermal protection, as well as output overvoltage protection by a second control loop ensure safe operation of the final system. The outputs deliver an electrically-isolated Safety Extra Low Voltage, SELV, (except models LXR/LXN70) and low output noise. They are no-load, overload, and short-circuit proof. The electronically controlled short-term peak power capability of up to 50% of the rated output power enables the front end converters to deliver additional power to start-up motors or to safely operate subsequent circuit breakers. Built-in large sized output capacitors absorb possible reverse energy, which may be caused by quick deceleration of electromagnetic drives connected directly to the output. A green LED at the front cover displays the status of the output(s). The Convert Select Series was designed according to all relevant international safety standards. The converters are approved by TÜV and UL, and are UL 508 listed. Adequate clearances and creepage distances allow operation in pollution degree environment (with AC input). All board assemblies are coated with a protective lacquer. Table of Contents Page Page Description... Model Selection... Functional Description...

The thermal concept allows operation at full load up to an ambient temperature of 60 C in free air without forced cooling. A rugged DIN snap-fit device allows easy and reliable fixing onto the various 5 mm DIN-rail models. The converters are fitted with cage clamp terminals easily accessible from the front. System connectors with screw terminals for use with preassembled harnesses, external adjustment of the output voltage, as well as various auxiliary functions are available as options.

Models with four powertrains have one or two outputs. Double-output models exhibit individual control of each output. The input voltage is fed via fuse, filter, and rectifier to the powertrains with main transformers designed in planar technique. The input filter with very small input capacitance generates virtually no inrush current. An input transient suppressor protects the converter against high voltage peaks and surges. Input over- and undervoltage lockout as well as input current limitation protect the converter from operation outside of its specification. The input voltage waveform is sensed by the primary control logic to allow active power factor correction, forcing the input current to follow the input voltage waveform. The secondary side of each main transformer supplies via the rectifier diode a large electrolytic output storage capacitor providing for the hold-up time. Double-output models exhibit an individual control logic for each output. The output voltage and the output current are measured and fed back to the primary control logic via an optocoupler. A second control loop monitors the output voltage. It disables the output in the case of a failure in the control logic and limits the output voltage. Built-in temperature sensors monitor the internal temperature of each powertrain. If the temperature exceeds the limit, the converter reduces the output power continuously to keep the temperature below its limit. A green LED on the front cover confirms the presence of the output voltage(s). The R input (option R, M, or M) allows for external adjustment of the output voltage by means of a resistor or an external voltage source. An external sensor can be connected to the R input and allows for temperature-controlled battery charging; see Accessories.

The powertrain temperature depends on the output power, the input voltage, and the cooling method. At low input voltage the losses increase. At the maximum specified environment temperature T A free air convection cooling might be insufficient. As a result, the output power has to be reduced according to the tables and 5. Note: The measurements have been made at the approval tests with free air convection cooling according to UL 60950, specified ambient temperature T A, and with the converter built in a cardboard box according to UL 508 and a specified temperature outside the box T out. The tables give a correlation between T A or T out and the case temperature T C (measuring point T C see Mechanical Data). For models not specified, please contact Power-One. Input Fuse and Protection A slow blow fuse (Schurter T0A, 5 0 mm), protected by a sleeve, is connected in the line input. For DC input voltages above 50 V an external DC fuse or a circuit breaker must be installed; observe the Installation Instructions. Converters with option F have fuses, one in each input line. The D C input voltage for all converters with option F is limited to 50 V. A VDR and a symmetrical input filter form an effective protection against input transients. An under- and overvoltage lockout protects the converter, which is disabled below V i min and above V i max by an internally generated inhibit signal. The built-in bridge rectifier provides reverse polarity protection at the input if operated from DC.
