DevreUsta:Electrical Simulator

DevreUsta is the most comprehensive and professional mobile electrical simulation and calculation app developed for electrical engineers, technicians, and students. Build electrical circuits that comply with industrial standards, test them, and accurately calculate all the parameters required in the field within seconds.
​⚙️ FREE DESIGN CIRCUIT SIMULATOR
Draw your own electrical control and power circuits exactly how you want them. Build your panel by dragging and dropping contactors, relays, timers, motors, and buttons from the palette. Make your connections and press the "Run" button to instantly simulate whether your circuit operates safely and flawlessly.
​🔢 PROFESSIONAL ENGINEERING CALCULATIONS
No need to carry manuals to the field or project sites. Calculate with a single tap using built-in tools:
• Cable Cross-Section & Voltage Drop: Find the ideal cross-section based on cable distance, current, and copper/aluminum conductor preference in accordance with IEC standards.
• Current & Power Calculations: Apparent/active power and nominal current calculations for 3-Phase and 1-Phase asynchronous motors.
• Motor RPM: Determine the synchronous and rotor speed (rpm) based on the number of poles, frequency, and slip rate.
• Power Factor Correction (PFC) & Capacitor: Determine the required reactive power (kVAR) to improve to the desired power factor (cosφ).
• Component Sizing: Automatically view the ideal ranges for Thermal Relays, Fuses, Motor Protection Circuit Breakers (MPCB), and Contactors (e.g., In × 1.15) for all calculation results.
​📖 STEP-BY-STEP GUIDE & HARDWARE DICTIONARY
Learn about Direct-On-Line (DOL) starting, Star-Delta starting, Soft Starters, and Variable Frequency Drive (VFD) equipment. Quickly understand the functions of industrial switchgear components with the built-in Technical Dictionary.
​💾 SAVE YOUR CIRCUITS
