PWM Regulator Steca PR1010 12/24V with Display
Modelo: PR1010- Sku: STECREG005
- Vendor: Steca
Specifications
Product Description
The Steca PR1010 PWM Regulator 12/24V with Display is the entry point of the PR 10–30 series, renowned for its reliability and especially precise battery control. Its shunt topology with MOSFETs and the multi-stage PWM algorithm optimize recharging and extend the service life of 12 or 24 V batteries, detected automatically. It incorporates the Steca AtonIC (SOC) system, which determines the state of charge with great accuracy and displays it on a graphical LCD display along with digital values for voltage, current, and energy. Additionally, it includes a data logger (resettable energy counter), self-test, and a comprehensive package of electronic protections for safe operation at all times.
Main Features
- Nominal current: 10 A for 12/24 V systems (automatic detection).
- Technology: PWM in shunt topology with MOSFETs; bulk/boost/float charging and monthly equalization.
- Graphical LCD display with Steca AtonIC SOC indicator, V/A/Wh readings, and button-operated menus.
- Integrated data logger (resettable accumulated energy) and self-test with fault messages.
- Programmable functions: evening/night/dawn light, load disconnection by SOC, automatic reconnection, and manual load switch.
- Protections: overload, deep discharge, reverse polarity, short circuit, over/undervoltage, overtemperature, night return, and electronic fuse.
Advantages or Benefits
- Protects the battery with precise voltages, thermal compensation, and monthly equalization that reduces sulfation.
- Total control from the LCD: real state of charge, energy, alarms, and simple programming via buttons.
- Superior safety: multiple electronic protections and automatic load disconnection/reconnection.
- Error-free installation thanks to 12/24 V detection and large terminals for robust wiring.
- Low self-consumption and IP31 design, ideal for autonomous equipment requiring high efficiency.
Purpose or Applications
Perfect for small off-grid solar systems: LED lighting, telecommunications, signaling, cabins, boats, and motorhomes. Its display facilitates maintenance and diagnostics in installations where the user needs to see the system status at a glance.
