The general direct current power supply can only offer the electric current of single direction, and the operating range of series BA crosses over 4 quadrants, so not only can offer positive voltage and negative voltage, but also can supply (Source) to the electric current , absorbent (Sink) .

Second, products characteristic



Apply to the extensive field
BA4825 BA4850
Offer the stable output
BA serial high-speed the intersection of bipolar and power can punish from direct current to highest 50MHz signal multiply frequency, high speed, upper voltage one ' Maximum 300Vp-p) , can output bipolar ' Plus-minus bipolarity) Power amplifier of the electric current of voltage. The general direct current power supply can only offer the electric current of single direction, and the operating range of series BA crosses over 4 quadrants, so not only can offer positive voltage and negative voltage, but also can supply (Source) to the electric current , absorbent (Sink) .
BA4825 BA4850 Frequency bandwidth DC- 2MHz DC- 50MHz High output voltage / electric current 100Vrms (300Vp-p) ,0.5Arms 20V, 1A The climbing speed is high 500V / s 6000V / s Output impedence Under(typ.) 0.5 +1.5 H Under(typ.) 3.3 +0.01 H Bipolar output Can supply (Source) Absorb (Sink) Positive negative voltage, 4 quadrants of the electric current run Abundant function Output the switching functionality of polarity, output area switching functionality, output and monitor external control, DCbias of the function, output ON/OFF (bias) Addition operation function, DC deflect and adjust the function Output the switching functionality of polarity
External control of output ON/OFF
DC deflects the regulating function
The power of high-speed bipolar is besides the BA series products, having and its frequency domain, Each not identical HSA series products (all 6 kinds of series of products) such as output voltage, the output current,etc. . In order to choose to be most suitable for your aircraft type, please consider the HSA series products together too.

Third, detailed parameter of products

Power of high-speed bipolar Series BA
Suitable for electric capacity inductive load
Generally speaking, if drive the load with capacitor or inductance coil with the AC supply, will result in coming from supporting the reverse direction electric current of one side. It may be unable to drive if in such cases, with the conventional power summing amplifier. But if adopt the products of series BA, even in the " absorbs " contrary to direction of the electric current of voltage (Sink) Can run too under the situation. So, as to the electric capacity inductive load such as piezoelectric element and inductance coil, also can run steadily ' Export) .

Wide-band to take the high-speed upper voltage
The frequency bandwidth of BA4850 is that DC- 50MHz, climbing speed are 6000V / s, even can reproduce fast pulse signal and complicated undulate signal of rising faithfully. The frequency bandwidth of BA4825 is that DC- 2MHz, highest output voltage are 300Vp-p, even and reveal the components and parts to the large-scale piezoelectric element, also can be rich in the leeway to drive richly. Because no matter which kind of model can begin with direct current, export, can realize for add waveform and plus-minus antisymmetrical corrugate magnification that deflect easily.

Low output impedence
In the whole frequency band, keep extremely low output impedence (BA4825 is typ under 0.5 + 1.5 H) . Insert and support the voltage caused and drop Damien through minimum inhibition, can draw its power to the maximum extent.

Abundant and a lot of function Alter the quantum switching functionality of the output area *1 Add direct current outputting ' Bias) DC bias addition operation function *1 Make DC included in the output deflect to deflect the regulating function for zero DC Allocate output voltage monitor terminal (BNC, monitor than 1/100) *1

Fourth, products application note

Power of high-speed bipolar Series BA
The drive of the piezoelectric element is appraised While driving and appraising the piezoelectric element using and pressing the electric transducer, pressing the electric actuator etc., need upper voltage and high speed performance. Series BA not only the voltage outputted is high, but also the impedance minima exported, so the piezoelectric element of very big electrostatic capacity also can get good step response.
The test of the components and parts of the display screen is appraised FED, liquid crystal homedric display screen, it drives to need upper voltage, it responds to characteristic appraisal to need high-speed climbing rate. Adopt the BA series products, utilize its high voltage output and high characteristic of the climbing speed, can test and appraise accurate drive.
As the power amplifier of pulse signal generator of happening device of the signal While appraising the power components and parts characteristic, want multiply frequency, upper voltage, large electrovalence power components and parts characteristic, want, high , form descent. Utilize characteristics such as multiply frequency, high speed, high voltage output of the BA series products,etc., can carry on appraisal and test of the components and parts with various waveforms, various pulse modes, and arbitrary waveforms.
Magnetization characteristic (B-H curve) of the magnetic material Measurement Can be used for measuring B-H curve of magnetic material such as ferrite and non- crystal material. Because the BA series products possess and measure the high frequency ( 50MHz) that B-H contours need , characteristics such as the high voltage output, high stability to inductive load,etc., so can carry on the measurement with superior reproducibility.
