M/s Mahesh Electrical Instruments - Electrical Components

We are well reckoned as one of the supreme Electrical Load Banks Manufacturers and Exporters from India. ME Load Banks are single phase and three phase variable Lamp or resistor or capacitor or Induction load housed in metal case as shown in the diagram. Our Portable Load Banks are provided with castor wheels (except Induction Load) for easy handling. Ammeters and Voltmeters are provided on the front panel to indicate the current and voltage respectively. Also heavy-duty Porcelain switches with bakelite top and inner brass contact or Anchor Switches or MCBs (As per the load capacity) are provided for safety. For Mains ON, MCB is provided. The Load Banks are used to simulate load conditions to test Voltmeters, Ammeters and Wattmeters. Load can be simulated by using the load switches provided on the bench. Total load simulated is sum of the loads of all 'ON' switches. The pictures shown are a three in one unit comprises of Capacitor, Induction and Resistor loads (in order) in single Load Bank. Load Type:- In resistance Load Bank Resistor wire as per required capacity is wound on the porcelain tube; in the same manner Bulbs are provided for bulb load bank (LAMP Bank) and Capacitor are provided for Capacitance load bank. Induction Load Bank is smoothly variable, core balance type inductive load. In this type, the load is increased or decreased by increasing or decreasing the air gap between the coils. In this Rotating knob is provided on the top of the panel for operating the air gap. Operating:-Before switching on the load bank, put all load switches in 'OFF' position. In induction load bank, keep the Coils in closed position, Switch on the Load Bank. Switch on the load switches one by one till the required load is simulated. For Induction Load Bank rotate the knob to increase the air gap and current will start increasing smoothly. Load Voltage & Load Current will be indicated on the Voltmeter & Ammeter respectively on the panel.

The Portable Resistive Load Bank is designed for electrical load testing and verification, operating at a voltage rating of 230V, 400V, or 415V AC in single-phase or three-phase configurations. It supports power capacities typically ranging from 5 kW up to 500 kW, with adjustable load steps in defined increments such as 1 kW or 5 kW. The frequency of operation is 50 Hz or 60 Hz, depending on application requirements. The load applied is purely resistive (ohmic), converting electrical energy into heat using stainless steel or nichrome resistor elements. Cooling is achieved through high-performance axial fans to maintain safe operational temperatures, with resistor temperature rise reaching approximately 250C to 400C. The enclosure is made of powder-coated steel or aluminum and rated between IP21 and IP55 for protection against environmental exposure. It is designed for portability, often mounted on heavy-duty wheels or equipped with lifting handles for field use. Safety features include thermal protection, airflow loss sensors, overcurrent trip, circuit breakers, and emergency stop controls. The unit is operated via a manual or digital control panel with real-time voltage, current, and power metering. Suitable for generator, UPS, and electrical system testing, it is a compact and rugged solution for on-site commissioning, maintenance, and performance evaluation tasks.
