What CONTROLES Y SERVICIOS, S.A. does

CONTROLES Y SERVICIOS, S.A. (CYS) is a privately held Mexican industrial electrical equipment manufacturer founded in 1972 and headquartered in Atizapán de Zaragoza, Estado de México. The company designs and builds four core product lines: power resistors (ground fault protection, dynamic braking, and industrial control), electromagnets (Magnetech brand) for scrap and bulk material handling, electrical equipment for overhead cranes (bridge, trolley, and hook controls plus accessories), and controls for stationary wound rotor motors used in rolling mills, mine winches, and crushers. Engineering processes are validated at LAPEM and CENAM, and the company is ISO 9001:2015 certified.

CYS sells on a direct, sales-led basis primarily to Mexican industrial customers in power generation, steel, mining, ports, and heavy industry (cement, sugar), with project-based custom product development and long-tenured customer relationships — most notably a 40+ year engagement with Voltran. Products are largely custom-built, with no public pricing and revenue generated through one-time hardware sales and supporting engineering services. The company distributes third-party branded components (Reuland motors, GE DC motors, Hubbell, Ametek Gemco, Gleason Reel, Mondel) alongside its own manufactured goods.

Export operations since 2009 (Canada) and 2014 (Middle East, Central America, Caribbean) run through OEM channels. The company has no disclosed headcount, no outside investment, no recent M&A activity, and a minimal digital marketing footprint, relying instead on industry reputation accumulated over 52+ years. Its strategic posture is that of a stable, owner-operated niche industrial manufacturer.

Brands

• CYS: Trade name / abbreviation for Controles y Servicios used on the company website and marketing materials.

Products and services

• Power Resistors (Resistencias de Potencia) High-capacity power resistors for protection in electrical substations and industrial applications, for continuous or intermittent service. Encompasses ground fault protection, dynamic braking resistors for inverters, and industrial control resistors for voltage drops, reduced voltage motor starting, transformer neutral grounding, battery discharge, and dynamic braking applications.
• Ground Fault Protection Resistors (Resistencias de Puesta a Tierra) Ground fault protection resistors for limiting fault current in transformers. Available in models RG (4.16–34.5 kV, >100 Amp), RGT (with zig-zag transformer), HRGT (4.16–34.5 kV, <15 Amp), and HRG (480V, <15 Amp) for substations and industrial applications.
• Industrial Control Resistors (Resistencias de Control) Industrial control resistors including stamped (Ri2t), wire (C57), tubular (CT), and helical (H) models for voltage drops, reduced voltage motor starting, transformer neutral grounding, battery discharge, and dynamic braking applications.
• Dynamic Braking Resistors for Inverters (Resistencias de Frenado Dinámico de Inversores) Dynamic braking resistors for inverter applications that dissipate regeneration energy to protect inverters from overvoltage when motors act as generators.
• Electromagnets (Electroimanes) Electromagnets for handling scrap metal, ingots, billets, plates, and borings. Heavy-duty, impact-resistant, sealed units with class H insulation and patented core design to maximize load-to-weight ratio, including Magnetech brand units.
• Overhead Crane Electrical Equipment (Equipo Eléctrico para Grúas Viajeras) Complete electrical equipment for overhead cranes including controls, accessories, and components for bridge, trolley, and hook operations in industrial facilities, ports, and steel mills.
• Wound Rotor Motor Controls (Controles para Motores Estacionarios de Rotor Devanado) Controls for starting and speed regulation of wound rotor motors in stationary machinery such as rolling mills, mine winches, and crushers.
• Bridge and Trolley Control Modelo MX-10 (Puente y Carro MX-10) Control for wound rotor motors in bridge and trolley of overhead cranes. Regulates motor speed by adding or removing resistances from the secondary circuit, with plugging relay for safe reversing.
• Hook DC Control Modelo MX-111 (Gancho CD MX-111) Direct current motor control for crane hooks. Regulates hook lifting speed by controlling armature resistances, with automatic braking during lowering through regeneration.
• Bridge and Trolley Inverter Control Modelo MX-18 (Puente y Carro Inversor MX-18) Control for squirrel cage motors in bridge and trolley using inverters for speed control with programmed ramp braking through regeneration.
