Direct Digital Synthesis Signal Generator

• Low Distortion SFG-1000 Series, an economic function generator with high accuracy and high stability output, is designed based on the DDS (Direct Digital Synthesis) technology embedded in a large scale FPGA. The frequency range of 3 MHz and the output waveform selection as Sine, Square, Triangle and TTL of SFG-1000 Series adequately provide the fundamental features to ensure high confidence for the test results. The DDS technology at an affordable price gives a high-value solution to the users who need a signal source for accurate but unsophisticated measurement applications.

Stable Signal Source:

• The frequency drift and the amplitude instability of conventional signal source sare fatal uncertainties to the high-accuracy measurements. employs PLL(Phase-Locked Loop) circuitry to generate a stable waveform at 20 ppm accuracy & stability covering the frequency range from 0.1Hz up to 3MHz. When is utilized to conduct experiments in the laboratory, it secures the signal sourcere liability, which is beyond the reach of any traditional signal generators.

Low Distortion:

• To most of the test engineers, it is always an annoyance trying to get rid of the ringing coming from the signal source being usedto stimulate the DUT. The high precision measurements need to employ a signal source without the existence of harmonic components, which adhere to the oscillator of conventional signal generator circuit.
• SFG-1000 Series, built over a DDS platform,generates the waveform through high performance DAC and high-speed comparator to effectively avoid the generation of harmonic components.Utilizing direct digital synthesis technology,SFG-1000 Series provides an output waveform with 55 dBc low distortion ranging from 2m Vpp to 10 Vpp output level. At the pressof a button, you get a stable and high purity output signal from SFG-1000 Series right away.

Applications:-

Primary Injection Testing:

• Almost all electricity supply protective equipment is fed from a current transformer on the supply cable or busbar. Primary current injection testing checks all the components of the protective system. A high test current, enough to cause the protection equipment to operate, is injected into the supply cable. Time takenfor the protection relay to operate is then measured.

• Udey PCT is essential when commissioning new protection systems and after major repair and component replacement, since it tests the whole system.

• Maintenance and routine testing of protective devices and systems by means of primary current injection, timing tests on protective relays- both magnetic and thermal types, current transformer ratio testing etc.

Description:

• Udey PCT series comprises of two units: 1) a control unit and 2) a loading unit. Thus making the tester compact and portable. Four models are available with outputs from 250 A to 3000 A. The control unit offers a current output of 0-10 Volt at 50 Amp or 0-5 Volt at 100 Amp. Additionally, a separate voltage output of 0-250 V AC is available for testing voltage operated relays coils or checking the magnetization characteristics of current transformers.

• Current and voltage outputs are varied from the output controller. The output current is supplied through wing nut bolts to the low inductance leadset (available optionally). The voltage output has a separate pair of terminals. Each set has a built-in multi range timer.

• All current and voltage levels are displayed on digital LED meters. The elapsed time measured by the timer is also displayed on 4 digit LED display.

• Circuit protection is by circuit breaker in input. Controlled switching ensures that, in the event of power failure or timer cut off operating, the output cannot be re-energized until the controls are reset, thereby offering protection to the equipment and the operator.

• The mains supply for the tester is 240 volts, plus 10 % minus 6 %. For 110 volt input operation, an input adaptor can be supplied. The control unit houses all necessary controls and metering for the complete equipment. The output voltage and currents are indicated on digital panel instruments.

• Automatic control has been provided such that the selected output can be switched off once the device under test has operated. The automatic control can be switched in and out of circuit for the selected output, this enables setting up tests to be performed.

• The control unit is provided with a crystal time base timer for timing relays whose contacts are either normally open or normally closed.

• The control unit and loading units are housed in robust cases complete with fold away lifting handles.
