Distinctive Features
PCD-03 Series
Adjustment of a high-voltage pulse either directly on the board (through built-in potentiometer) or remotely;
To know more about PCD-03 see technical specifications
1 Is set from the built-in potentiometer.
2 Depends on the load inductance and output voltage amplitude.
3 Is set by manufacturer.
4 Delay depends on the trigger pulse. The higher trigger amplitude the shorter delay.

Vigitek, Inc. designs and supplies optical, electro-optical, and laser-related products and subsystems, and also supports OEM and custom developments for biomedical and industrial applications.
Our catalog includes engineering-grade components such as diode drivers, capacitor charging power supplies, controllers, and related electro-optical modules. Availability and configuration options vary by product.
Yes. We support OEM and custom configurations for many products. Share your target specifications (electrical output, pulse parameters, interfaces, packaging, and any test/documentation needs), and we’ll recommend the best-fit option and quote accordingly.
Yes. Send a short description of your application and key requirements (power, voltage/current range, pulse width and repetition rate, cooling constraints, interfaces, and intended use). We will help you select the most appropriate solution.
When applicable, we can provide user documentation and test information appropriate to the product and your requirements. If your program requires specific documentation or traceability, mention it when requesting a quote.
We can assist with integration questions, configuration guidance, and troubleshooting. For the fastest support, include your order/invoice number and product model/serial number (if applicable), plus a clear description of operating conditions.
Yes. We ship within the U.S. using common parcel carriers (UPS/FedEx) and LTL freight for larger items when needed. Shipping options and costs are provided with your quote or order confirmation.
Lead times depend on the item and configuration. Standard items generally ship within the lead time shown on your quote. Custom or build-to-order items may require additional manufacturing and test time.
Many Vigitek products are configured to match specific system requirements (electrical output, pulse parameters, interfaces, packaging, firmware, and test requirements). Publishing a single price can be misleading, so we provide quotes that match your exact application and quantity.
In most cases, we can provide a quote quickly once we have the key requirements (product/configuration, quantity, and ship-to location). For custom or highly specialized requests, we may ask a few technical questions to ensure accuracy.
Yes. Pricing often improves with higher quantities and ongoing production. Let us know your forecast and we’ll quote the most appropriate tier.
Often, yes. If a standard configuration meets your needs (or if certain options aren’t necessary), we’ll suggest a simpler, more cost-effective approach.
Custom and OEM developments are quoted based on scope, requirements, validation/testing, and deliverables. We’ll outline what’s included so you can compare options clearly.
Warranty and return eligibility vary by product and are confirmed on your quote or order confirmation. Returns generally require prior authorization. If you believe an item is defective or damaged in transit, contact us promptly with details and photos.
Vigitek, Inc. aims to ensure you receive products that meet specifications and perform as intended. Because many items are technical, configured, or built to order, returns are handled through a Return Authorization (RA) process.
Please contact us to request an RA before returning any item. Returns sent without prior authorization may be refused.
If a non-defective return is approved, the return window and shipping address will be provided with the RA. Items received outside the approved window may be refused.
After inspection/testing, we will determine the appropriate outcome based on the issue and the terms of your purchase, which may include repair, replacement, credit, or refund (as applicable). If no fault is found or the issue is outside warranty/return eligibility, evaluation fees and return shipping may apply.
If you are unsure whether an item qualifies for return, contact us before shipping anything back.
Vigitek, Inc. provides a limited warranty on select products we manufacture and sell (for example: diode drivers, capacitor charging power supplies, and controllers). Warranty coverage and duration may vary by product and will be confirmed on your quote, order confirmation, or invoice. For custom/OEM developments or engineering services, warranty terms are governed by the applicable project agreement.
This limited warranty covers defects in materials and workmanship under normal use and service, when the product is installed, operated, and maintained according to Vigitek documentation or written instructions. Warranty coverage begins on the date of shipment or delivery (unless otherwise stated in writing).
Please contact us to obtain a Return Authorization (RA) before sending any product/part back for evaluation.
Include your order/invoice number, product model and serial number (if applicable), a clear description of the issue, operating conditions, and photos/video when possible. We may ask you to perform basic troubleshooting steps to speed up resolution.
If the issue is determined to be a covered warranty claim, Vigitek will, at our option:
Repaired or replaced items are covered for the remainder of the original warranty period, unless otherwise required by law.
Products returned for evaluation must be packaged appropriately to prevent transit damage and must display the RA information as instructed. Items returned without prior authorization may be refused. Transit damage is not covered by this warranty.
Except as expressly stated above, this warranty is provided in lieu of all other warranties, express or implied, including (to the extent permitted by law) implied warranties of merchantability and fitness for a particular purpose. Some jurisdictions do not allow certain limitations, so parts of this policy may not apply to you.
Vigitek, Inc. ships within the United States. Shipping options, lead time, and costs depend on the product type, quantity, destination, and any handling requirements.
For shipping questions or special handling requests, contact us:
Many of our products are engineering-grade components (drivers, power supplies, controllers, and electro-optical modules) that are often configured to match a customer’s exact system requirements. Because specs, compliance needs, test requirements, and quantities can vary significantly, a single “list price” rarely reflects the best or most accurate cost for your application.
Tell us what you’re building and we’ll recommend the best-fit solution and provide a detailed quote.
