HV AC Voltage Test Systems
Fivestar HV Testing Equipment Co., Ltd.
FSHV offers three different types of AC voltage test systems, the conventional type is AC test transformer design, mainly for testing objects of medium & low capacitance products, particularly for tests requiring stable voltage even if the load changes under voltage (corona, wet & pollution tests) or when the load is inductive (like inductive voltage transformers). Another is AC resonant test systems, according to series resonance circuit XL=XC (2πfL=1/2πfC), by setting F frequency of power supply or L inductance of reactor, generate a pure sinusoidal waveform of the test voltage, and the required input power is only 1/Q. Variable frequency type operates in a frequency range from 20Hz to 300Hz, ideal for field commissioning test of power cables and GIS/GIL. Variable inductance type outputs continuous AC voltage of power frequency (50/60Hz), mainly for factory testing of high and ultra-high voltage cables, power transformers, GIS, etc.

Variable Power Supply
VS-10a
The VS-10a power supply is a light weight, portable, non-isolated “variable source” from 0 volts to 150 Vac or 0 volts to 150 Vdc and rated for up to 10 amps, thus the name VS-10a. It is comprised of an illuminated voltmeter that reads to the first significant digit, AC variable system output voltage, DC variable system output voltage, logic output voltage and one sense (continuity) contact monitoring points. Banana jacks for connection of test leads are spaced at intervals that allow the use of dual banana test plugs if desired. The VS-10a is protected by two levels of overcurrent protection; AC input, and ground fault protection by a GFCI. All circuitry is housed inside a custom designed case made from 16 gauge steel. An Internal fan dissipates heat buildup and exhaust through louvered side vents built into the case. The carrying handle is designed with a “spring return to rest” position and is padded for comfort. The case has been sized for optimum portability and is balanced from the handle during transportation. The case has a powder coated finish that is scratch, chemical and weather resistant. Rubber padded feet support the case when in the upright position and a convenience receptacle is located on the side of the case.

DC POWER
VARIABLE TRANSFORMER
Variable DC power supplies are AC to DC power supplies with a variable DC output. The output can be varied with a Variable Transformer (also known as variac). The Variable Transformer can be adjusted manually or with a motorized control. The AC input power can be single phase or three phases. With single phase AC input, the DC output ripple is very high (50%). With three phase AC input, the DC output ripple is low (5%). This would be a key benefit for selecting three phase AC input instead of single phase.

Heavy Duty Dynamometers
MD-7500-HD
Today’s Fleet Managers are faced with many challenges – most important of which is maintaining a healthy bottom line. With fuel costs at an all-time high, these challenges have become increasing difficult. Fleets being transitioned from fossil fuels to electric propulsion also face challenges with durability and range to make sure routes can be completed on time each and every day. To help combat these problems and others facing fleet managers today, Mustang Dynamometer offers the MD-7500-HD Series Chassis Dynamometer – which features the most advanced diagnostic capabilities in the industry. The MD-7500-HD is designed to simulate the driving conditions that fleet vehicles encounter on the road every day in a safe and controlled shop floor environment so that critical engine and drivetrain systems can be evaluated to insure vehicles are performing properly and at maximum efficiency. What’s more, the MD-7500-HD offers several levels of testing capabilities in a modular, compact package and with capabilities that can be upgraded in the future as your needs change. Every vehicle in your fleet can now be tested and validated before and after a repair to ensure proper diagnosis and repairs have been performed. In addition to testing repaired vehicles, the MD-7500-HD can be used to test vehicles on a regular basis as a preventative maintenance measure which decreases unexpected breakdowns and allows fleet management to control fuel costs while reducing repair costs. Periodic testing keeps fuel consumption to a minimum and helps technicians identify suspect components before they fail. A proactive approach to Fleet Service can prevent unexpected engine and or drive-train failure which saves organizations thousands of dollars in lost fair revenues. At the heart of the MD-7500-HD is a set of three air-cooled eddy current power absorbers. Each absorber, or brake, can hold up to 600-hp (total power of 1,800-hp) – more than enough to simulate a fully loaded transit bus. As the systems PAU’s (brakes) are air-cooled, no water is required to or from the device – eliminating the high cost of water consumption and/or the cost of an expensive water recovery system – which can sometimes exceed the cost of the dynamometer system itself. Mustang is the only company that offers a Universal Fleet Test Bed without water supply requirements. AC Motors can be added to simulate regeneration and validate range for organizations that have transitioned to carbon free electric propulsion. The 7500 is the best solution for fleet managers looking to improve their bottom line and offer disruption-free public transportation.
