SR3R - Universal switching stabilizer with the change of polarity / the regulator DC of motor
Regulator consists from SR3 of regulator with the additional board. With this supplement it possible will join SR3 on industrial PLC. Entry accepts 24V PWM for the defining speed also has yet two entries: RUN and REV. Them switch on the output also changes the direction. Change od direction is possible and without the switching off RUN of signal. Output then automatically turn off, and when the voltage falls below 0.5V relay changes the polarity of output and then again switches on the voltage outbound. Control PNP output uses for the feedback about the polarity of output.
Power supply: 24V~ / 30V=
Output: 0..24V= / 4A maxes
Entry speed: 24V PWM frequencies 20..50kHz, impedances 3300 ohma, time constant PWM of filter are 50ms
Entry RUN: 24V, impedances 10KR
Entry REV: 24V, impedances 10KR
Output REV: 24V / 10mA
I * R compensation for DC motor: 7R maxes
Regulable: I * R, Imax, Umax, Umin
Indications: green LED on the exit voltage (proportionally shine for Ui > 2V)
Exceptionally the stable regulation and by small turnings (10 % maximal speed).
Complex was able is he used as the stabilized power supply when I * R compensation eliminates.
Permanently maintains the short-circuiting outbound.
Little the warm-up regulator (Pd=f(Iout)), PD independent about exit or the entry voltage).
For the work with the current output smaller from 2A is not the necessary additional heat sink
Protections of motors from the too big current (SR3 limits current at accelerations) greatly makes longer lifetime the motor.
The constant maximal moment (Imax) decreases strike on the mechanical transfer and prevents breakdowns.
Dimension of complex: 100 * 205 * 53mm (W*L*H), option 100 * 128 * 93mm (W*L*H)
Price of finished complex with the additional heat sink SK88 / 37 (without the box): 640 HRK (85 euro)
Deadline production: 3 day
regulator DC of motor 24V for transportation mechanisms
regulator DC of motor milling machines 12 or 24V=
regulator DC of motor with the constant moment adjustable with Imax (for the tighten and safety at overloads).
DC power supply 24V instead 24VAC
on request was able order the board for the switching off of motor after the longer duration maximal the current (> the 30 second)
actively breaking the motor at reversals direction (the short-circuiting with the current limit) because of lowering times
the separable ordinal terminal (sauro) instead of standard without the additional heat sink SK88 / 37 for the permanent work on maximal 2A (20 HRK cheaper)
