Servo And VFD Filters
-
Operation of PWM-driven motors – servo motors and variable frequency drives (VFD) – causes several problems in equipment, including damage to the motor’s bearings due to leakage current causing electrical discharge machining (EDM) and damage to motor’s insulation. PWM motors also are a major source of EMI in equipment. These motor drive systems use pulsed power to drive the motors. As we are aware, the sharp edges of the pulses inevitably include high frequency components which can couple or radiate as noise to other parts of your system and cause unreliability, communication/control problems and EMC compliance issues.

Test Cells
-
LaplaCells provide a facility for the rapid and efficient testing of the EMC compliance of products. These cells offer a calibrated and screened environment in which radiated emissions can be measured and immunity to RF radiation can be tested. They exceed the requirements of IEC61000-4-20, thus affording compliant testing to IEC61000-4-3 and pre-compliance testing for radiated emission testing. The Cells are a modified form of GTEM cell, using a balanced dual septum design which maximises EUT volume for a given external size of cell, and dramatically improves field linearity. The EUT volume is fully lined in structural polycarbonate capable of supporting heavy products and access is via a large, full height door at the end of the cell. Adjacent to the door is the I/O filter compartment which can be customised to suit the users requirements. USB, RS232, Parallel, Ethernet, co-ax and other product specific filters can be added at time of ordering.

Power Amplifiers
-
The RF power amplifier range from Laplace is specifically designed for EMC Immunity testing according to IEC61000-4-3 and IEC61000-4-6. These are compact units with characteristics matched to the requirements of IEC standards. These RF amplifiers utilize fully isolated linear MOSFET or advanced GaAs FET devices, which provide high gain, wide dynamic range and excellent third order intercepts. High efficiency and reliable operation are achieved by employing unique RF combining circuits, RF microstrip networks, sophisticated thermal design, custom machined housing and heavy duty components. The high power RF amplifiers undergo extensive burn-in prior to final test and inspection.

RF Filters
-
RF Filters block unwanted frequencies when testing electronic devices for emissions during EMC testing. They attenuate unwanted frequencies and allow the desired signals through. The RF filters isolate the device under test from external RF noise, this increases the reliability and accuracy of the EMC testing by preventing out-of-band noise and harmonics.

DC Filters
-
This DC filter provides substantial noise reduction on DC power lines of up to 50V 9A. Filter provides noise suppression in both directions protecting your DC lines from noise generating by a particular piece of equipment or protecting your sensitive equipment from noise coming from DC power supply or other loads. DC filter provides noise suppression for both power lines – positive and negative, plus common-mode noise vs. ground. Filter uses plug-in terminal block for connections and mounting flanges for easy installation. Its rugged construction makes it easy to fit in many industrial tools.

Coupling Decoupling Network (CDNE)CDN
Emissions
-
CDNEs are based on the CDN as specified in IEC61000-4-6 (Conducted RF Immunity test). In this test, the CDN is used for the coupling of RF onto a cable. In principle, the CDN can be used in reverse, ie coupling any RF on the cable out to an analyser. In an earlier version of EN 55015, these CDNs were specified as suitable for measuring emissions. However, the current version of the standard specifies a CDNE which is essentially a CDN refined to deliver higher accuracy particularly at higher frequencies.

CDNs
-
Laplace supply a wide range of CDNs that are fully compliant to IEC61000-4-6. Laplace are unique in offering two other types. Both types are ‘versatile’ in that they are configurable, offering great flexibility in terms of the type of cable each model can be used with. This reduces the number of CDNs necessary to hold in stock. The final type is, in addition to being versatile, fitted with an output which monitors the RF level applied to the cable.

Clean Power Source
AC1000A
-
The AC1000 achieves its unique price/performance ratio by actively adjusting the incoming mains waveform to produce a clean output. Other suppliers use convertor techniques to completely recreate the output from scratch. Our solution delivers an output which achieves the required THD with the minimum of hardware and expense. It includes the ability to switch the correction in or out so that the original waveform can be observed and measured if required. Overload and thermal protection systems are built-in and produce an audible warning if activated.
