PWM Regulator Steca Solarix PRS1515 12/24V 15A
Modelo: Solarix PRS1515- Sku: STECREG002
- Vendor: Steca
Specifications
Product Description
The PWM Controller Steca Solarix PRS1515 12/24V 15A is designed for off-grid solar installations that require higher current without sacrificing simplicity and robustness. It implements a series topology with MOSFETs and multi-stage PWM control that protects and maintains the battery through boost, float, and monthly equalization, with temperature compensation. Its electronics integrate an automatic fuse, multiple protections, and intelligent load reconnection, while the multicolor LED display provides real-time information on operation, charge status, and alarms.
Main Features
- Working current: 15 A at 12/24 V with automatic recognition.
- Series PWM control with MOSFETs and optimized multi-stage charging.
- Comprehensive protections: overload, deep discharge, reverse polarity, short circuit, over/undervoltage, overtemperature, and night return.
- LED indicators for operation, SOC, and faults; automatic reconnection.
- Self-consumption <4 mA; IP31; negative or positive ground connection adaptable to the system.
- Project functions via Steca PA RC100 (night profile and threshold parameterization).
Advantages or Benefits
- Protects the battery and reduces maintenance with precise, temperature-compensated charging profiles.
- Supports higher loads (15 A) while maintaining size and ease of installation.
- Enhanced safety with electronic fuse and low voltage disconnection with automatic re-engagement.
- Quick system status reading without additional instruments thanks to multicolor LEDs.
- Scalable and adaptable through parameterization and optional dusk function.
Purpose or Applications
Suitable for field cabins, telecom, lighting, caravans, boats, surveillance systems, and light pumping. Excellent as a 15 A PWM controller in 12/24 V solar kits that prioritize reliability and cost-effectiveness.
