Adjustable Resistor 53 Ohm 225W – Tubular Wound (Used)
In the demanding world of power electronics and automation, flexible components are essential for calibration and maintenance. The Adjustable Resistor 53 Ohm 225W is a robust solution designed for engineers and technicians who require precise voltage and current control in thermally demanding applications.
Detailed Technical Specifications of the Adjustable Resistor 53 Ohm 225W:
Component Type: Adjustable Wirewound Power Resistor (Adjustable Wirewound Power Resistor / Power Potentiometer).
Maximum Impedance / Resistance: 53 Ohms (Ω) – Adjustable from 0 to 53 Ω by moving its center slider.
Rated Power Capacity: 225 Watts (W). Fully compatible and sufficient for systems requiring 200W.
Tube dimensions: 265 mm length x 29 mm outside diameter.
Coating: Vitreous enamel / high temperature silicone in dark green, typical of industrial standards for protection against moisture and dust.
Product Condition: Used / Tested. For maximum commercial transparency, this item is sold as used. It has no original box or visible markings. However, mechanically it is intact and electrically it has passed the multimeter tests, guaranteeing that the winding is not open (burned) and makes perfect contact.
Applications and Uses (What is this 53 Ohm 225W Adjustable Resistor for?):
The advantage of having a movable terminal allows this part to be extremely versatile in laboratories or production plants. It is mainly used as:
Voltage Dividers (Voltage Dividers): To derive and extract specific voltages from a high power main power supply.
Adjustable Phantom Loads (Dummy Loads): For performing custom stress tests on amplifiers, sources and electrical generators.
Motor Current Adjustment: For calibrating speed or starting torque on direct current (DC) motors.
Style and Manufacturing History:
Although the piece lacks a visible logo, its design emulates legendary U.S. industry standards (such as the classic series Dividohm Ohmite’s classic Dividohm series). The dark green color and rugged exposed stripe indicate that it was built to MIL-SPEC or generic industrial standards for high durability, intended to survive in control cabinets for decades.
(FAQ)
Q: Why is it sold as “used”?
R: We encourage total honesty in our e-commerce. Since the part does not have its original packaging, lacks printed markings and we do not know its previous history of use in machinery, we list it as used. However, it has been electrically tested to ensure it is fully functional.
Q: How do I set the ohm value of this resistor?
R: It has a metal clamp (cursor) in the center of the tube. Simply loosen the clamp screw, slide the clamp along the exposed strip until the desired value (between 0 and 53 ohms) is reached with a multimeter and retighten the screw firmly.
Q: Can I adjust the resistance while the equipment is on?
R: No. For operator and circuit safety, slider adjustment should always be done with the equipment fully de-energized.
