SM6000 DELTA ELEKTRONIKA BV DESCRIPTIONS 1) OUTPUT SM 15-400 SM 30-200 SM 45-140 SM 60-100 SM 70-90 SM 120-50 The SM15-400, SM30-200, SM45-140, SM60-100, SM70-90, SM120-50, SM300-20 and SM600-10 can either be used as a constant voltage source with current limiting or as a constant current source with voltage limiting. The change of mode occurs sharply at the crossing of the voltage and current settings. Figure 3 - 1 shows the output ranges.
DELTA ELEKTRONIKA BV 9) SM6000 ANALOG PROGRAMMING The output voltage and current can be programmed by an external analog voltage. This programming is very accurate and linear. The levels are all standardized on 5 V. Standard the SM300-20 and SM600-10 are equipped with the ISO-AMP, see next paragraph. For the other units, the inputs have a protection circuit formed by a series resistor and a parallel zener (see fig. 3 - 4). The capacitor limits the speed to a safe value.

DELTA ELEKTRONIKA BV 17) SM6000 REMOTE SHUTDOWN (RSD) A voltage of +4 V...+12 V on the Remote ShutDown input on the programming connector CON E will switch off the output of the unit. It is also possible to use a relay contact or a switch to shut the unit down (see fig. 3 - 11). In standby mode the power supply consumes very little power. 18) INTERLOCK The Interlock connector (CON A, rear panel) has 2 inputs which have to be connected together to turn on the output of the unit.
SM6000 22) DELTA ELEKTRONIKA BV RFI SUPPRESSION Both the input and output have RFI filters, resulting in very low conducted RFI to the line and load. Due to the output filter the output voltage is very clean, having almost no spikes. 23) OPERATING TEMP At full power the operating temperature range is –20 to +50 °C. From 50 to 60 °C the output current has to be derated linearly to 75 % at 60 °C (see fig. 3 - 15). These temperatures hold for normal use, i.e.
DELTA ELEKTRONIKA BV 30) SM6000 SERIES OPERATION Series operation is allowed up to 600 V total voltage. The power supplies can be connected in series without special precautions. For easier control, Master / Slave operation is recommended (see fig. 3- 18). By using the Master / Slave series feature a dual tracking power supply can be made with one unit as master and one as slave.
SM6000 33) DELTA ELEKTRONIKA BV VOLTAGE AND CURRENT LIMIT The Voltage Limit will protect your circuit from unwanted high voltages. A high output voltage could be caused by accidental interruption of leads, accidentally turning up the voltage potmeter, a programming error or a defect in the power supply. The Voltage Limit circuit uses a separate voltage divider connected directly to the output terminals. The Current Limit protects your circuit from unwanted high currents.
DELTA ELEKTRONIKA BV SM6000 OPERATING MANUAL 1) OPERATING THE UNIT FOR THE FIRST TIME Warning: carefully read the chapter "Safety Instructions" in this manual before operating the unit! • • • • • • • • • • • • • • • 2) Check there is no condensation on the unit. If there is, allow some time to dry. Check there is a link between + and S+ and between – and S– on the SENSE BLOCK (on rear panel). Check there is a link between the inputs of the Interlock (CON A).
SM6000 DELTA ELEKTRONIKA BV switch on will be the same as before switching the mains voltage off. 4) ANALOG PROGRAMMING • • • • • • • • • • 5) Set DIP switch 1 of SW1 in position UP to select CON E for programming. For SM300-20 / SM600-10 see paragraph ISO-AMP. Disable Keylock. Set the unit in REMOTE CV for voltage programming and/or in REMOTE CC for current programming. Use the REMOTE/LOCAL button and push this button several times until the right setting is activated.
DELTA ELEKTRONIKA BV 8) STATUS OUTPUTS • 9) Suggested circuit breakers for protection power supply The status outputs have a separate Ø connection (pin 8) to avoid unwanted offsets in the programming. This pin is protected with a 650 mA self resetting fuse (F27_2 on P598). REMOTE SENSING • • • • • • 10) SM6000 Remove the links on the SENSE BLOCK (on rear panel) and connect sense leads (thin shielded measuring wires) to S+ and S–. See fig 4 - 5 and fig. 4 - 6.
SM6000 DELTA ELEKTRONIKA BV After turning the units on again, the slaves will be in Remote CV mode and the Keylock (see previous paragraph 2) is activated. This is because the unit automatically detects the presence of the RJ45 connector in CON C (if this cable is connected to another unit). If the RJ45 connector is removed from CON C when the unit is turned on, the output will shutdown to avoid accidental damage.
DELTA ELEKTRONIKA BV SM6000 OPERATING AND STORAGE CONDITIONS 1) TEMPERATURE The operating temperature range at full load is –20 to +50 °C. But this temperature range only holds when the AIR-INTAKE and AIR-OUTLET are unobstructed and the temperature of the AIR-INTAKE is not higher than +50 °C. • Please note: a lower temperature extends the life of the power supply.
SM6000 DELTA ELEKTRONIKA BV TROUBLE SHOOTING 1) GENERAL In case you need assistance for repairing a unit, please contact our engineers using the address "Support@Delta-Elektronika.nl". • In case you want us to repair the unit, please first fill out the RMA-form before sending the unit to us. Adding a detailed fault description will help us to repair the unit as soon as possible. On our website www.DeltaPowerSupplies.com the RMA-form can be found under 'Support'.
DELTA ELEKTRONIKA BV 6) SM6000 MASTER / SLAVE PARALLEL PROBLEMS Check the voltage drop of the wiring between the master and the slaves is < 10 mV. • Check the wiring has a low inductance. • 7) OUTPUT VOLTAGE IS HIGHER THAN SET VALUE • 8) Check connections on SENSE BLOCK (on rear panel), For normal operation there should be a link between + and S+ and between – and S– (see also fig. 4 - 16). When remote sensing is used, check the wires of the sensing.
SM6000 DELTA ELEKTRONIKA BV CALIBRATION 1) GENERAL • 2) METER CALIBRATION • 3) The power supplies are factory calibrated and normally need no further calibration. Only in special situations (for example after repairing a unit) calibration can be necessary. DIGITAL METERS The full scale indication can be calibrated with R25_31 and R25_36 on P596 (see fig. 4 - 17). SPECIAL CALIBRATIONS The following calibrations must be done by qualified personnel only. Wrong calibration causes malfunction.
