Build It Online
Online Custom Power Supply System Builder was developed to assist design engineers meet market demands for fast delivery of customized, multiple-output power systems at off-the-shelf prices.

Through a series of intuitive steps, engineers can custom design dc-dc and ac-dc power supplies, high-voltage dc-dc and ac-dc power supplies, redundant systems and unregulated power supplies. The custom-designed units are notably available in voltages ranging from 0-30 kV, with one to 30 outputs, and with 0.025-2400 W output power. Users can input special instructions or speak to an available engineering design consultant anytime throughout the process.

UPS Management Fundamentals
From plug and receptacle charts and facts about power problems to an overview of various UPS topologies and factors affecting battery life, you'll find a wealth of pertinent resources designed to help you develop the optimum solution.

UPS and Power Management Fundamentals Handbook also includes valuable, real-world case studies that showcase exactly how you can develop the best power protection solution. The handbook is a one-stop source for essential information, whether you need power protection for small, medium or large data centers, healthcare facilities or other environments in which ensuring uptime and safeguarding data is critical.

Reduce Input Current Harmonics
Non-linear loads are loads in which the current waveform does not have a linear relationship with the voltage waveform. Non-linear loads generate voltage and current harmonics, which can have adverse effects on equipment used to deliver electrical energy. Power delivery equipment is subject to higher heating losses due to harmonic currents consumed by non-linear loads. Harmonics can have a detrimental effect on emergency or standby power generators, telephones and other sensitive electrical equipment. When reactive power compensation in the form of passive power factor improving capacitors are used with non-linear loads, resonance conditions can occur that could result in even higher levels of harmonic voltage and current distortion, thereby causing equipment failure, disruption of power service and fire hazards in extreme conditions.

This white paper discusses ways to control and reduce these dangerous harmonics.

Specify Your Ideal DC UPS
Microprocessor-based industrial controls — PLCs, industrial computers, HMIs, drives, motion controllers and sensors—are the foundation of high productivity, quality and competitiveness.

The one universal factor that can and will disrupt microprocessor-based controls and cause downtime is power quality. Since industrial electrical systems frequently experience voltage fluctuations, harmonic distortions, noise and short- or long-term power outages, it is essential to ensure maximum uptime by specifying an uninterruptible power supply (UPS) for your application. Specifying the optimum UPS for a control system can be one of the most cost-effective investments available.

But how do you do it? This white paper outlines the advantages and disadvantages of AC and DC UPSs, important things to know about batteries, key features for operations and diagnostics, and more important information to help you choose the best UPS for your purposes.
