Induction Heating & Melting Capacitors

RAM Series Medium Frequency Induction Heating Capacitors

Designed for medium frequency induction heating systems requiring reactive power compensation. Supports metal smelting, forging, heat treatment, and surface quenching applications across aerospace, automotive, heavy machinery, and metal processing industries.

Product Overview

The RAM series delivers rated voltage of 2200 V with reactive power capacity of 3960 kvar at 3000 Hz, supporting high-power induction heating applications in complex industrial environments.

The capacitor elements are constructed using metallized polypropylene film with a self-healing dielectric layer. This construction limits fault current in the event of a dielectric breakdown, allowing the capacitor to continue operation after minor insulation failures. The housing incorporates forced-air cooling with optimized fin geometry and is constructed from materials that facilitate heat dissipation while maintaining electrical insulation properties.

Three configuration options are available to accommodate different system requirements: single cooled-live case design with sub-sections (one terminal connected to casing), single cooled-isolated case design with sub-sections (all terminals isolated), and double cooled-isolated case design without sub-sections (all terminals isolated). This flexibility allows integration with various system grounding requirements and thermal management approaches.

Installation & Operation Notes

01

Cooling Requirements

Forced-air cooling with minimum airflow specified per model. Single cooled configurations require 200 CFM minimum; double cooled configurations require 350 CFM minimum. Intake air temperature should not exceed 40°C for rated operation.

02

Mounting Orientation

Install vertically with terminals oriented upward to allow natural convection to assist forced airflow. Horizontal mounting requires cooling system verification to ensure proper airflow distribution across the capacitor element stack.

03

Electrical Connections

Bus bar connections must be torqued to specified values to minimize contact resistance. Loose connections cause localized heating, potential performance degradation, and reduced service life. Use appropriate torque tools and follow manufacturer specifications.

04

Grounding

Live case configurations require casing grounding per local electrical codes. Isolated case configurations require proper insulation coordination with adjacent equipment to maintain system integrity and safety.

05

Environmental Conditions

Indoor installation only. Ambient temperature range: -25°C to +50°C. Relative humidity below 85% non-condensing. Avoid corrosive gases, conductive dust, excessive vibration, and direct sunlight.

Frequently Asked Questions

What is the difference between live case and isolated case configurations? +
In live case configuration, one terminal is internally connected to the capacitor casing, requiring the casing to be grounded. This design is typically used in systems where the capacitor is part of a grounded circuit. In isolated case configuration, all terminals are isolated from the casing, providing flexibility for floating or ungrounded system designs where grounding coordination requires complete isolation.
What does the "S" designation in the model number indicate? +
The "S" indicates single cooled configuration with sub-sections. This means the capacitor has internal sub-divisions for fault isolation and uses a single cooling system. "D" indicates double cooled configuration without sub-sections, providing enhanced cooling for higher power applications where thermal management is more demanding.
Can these capacitors be used at frequencies other than 3000 Hz? +
The RAM series offers models ranging from 300 Hz to 50 kHz, covering low-frequency to high-frequency induction heating processes. The specific RFM 2.2-3960-3.0S model is optimized for 3000 Hz operation. For other frequency requirements, please refer to the full model range for suitable alternatives with matching voltage and power ratings.
What is the expected service life under continuous operation? +
Service life is influenced by operating temperature, voltage stress, and duty cycle. Under rated conditions with proper cooling, the design life exceeds 80,000 hours. Regular monitoring of capacitance and dissipation factor is recommended to track degradation and plan maintenance intervals. Operating at temperatures below the maximum rating significantly extends service life.
What type of cooling system is recommended for these capacitors? +
Forced-air cooling with filtered intake air is recommended to prevent dust accumulation on cooling surfaces. Single cooled configurations require minimum 200 CFM airflow; double cooled configurations require minimum 350 CFM. The cooling system should be sized based on the specific power rating and ambient temperature conditions. Regular filter cleaning or replacement is necessary to maintain cooling efficiency.
