Complete Load Bank Soluions

We have manufactured load banks for 10 years,

and our Chinese brand has become Chinese a

renowned brand. Our main projects are OEM for

some major PLC’s with a series of load banks from

1kW to 60MW. We have a team of specialized

designers and electrical technicians along with

R&D, and we are developing a remote method of

controlling banks without an actual presence.

JMHING (HK) Electronic Technology Co., Ltd. , is

an established hi-tech brand with over 10 years

manufacturing experience, specializing in the

development and manufacture of stable continuous

and variable load banks with tailor-made testing

solutions to meet all requirements. JMHing is 100%

committed to maintaining the highest standards that

you have every right to expect throughout Design,

Manufacture and Product Support.

We have enjoyed some long cooperation’s with

some brands you may recognize and specialize in

developing bespoke ranges for companies from the

ideas level through to manufacture and installation.

With over a decade of extensive experience

allowing JMHing the capability to satisfy any load

bank design requirement, from standard size

resistive and reactive load banks to

custom-designed load banks of any size at any

voltage and frequency, from the basic manual

control to automatic or TCP/IP remote control. If you

have any questions or requirements, please contact

us without any hesitation.

When you build a data center, any unexpected glitch during commissioning can cause serious project delays, wasted

productivity, and significant budget overruns. So integrating rack mounted load banks into the design phase can help

our data center clients keep projects on budget and on time.

JMHing’s rack mounted load banks are designed especially for data center commissioning testing, they precisely

simulate high density server loads and air flow for the most accurate and complete hot aisle/cold aisle testing. We

provide resistive, reactive and capacitive load banks in low or medium voltage to cover the entire scope of your

commission and testing requirements. Our dedicated solutions for data center commissioning include:

Purely resistive load bank is the most common type of load bank, and

it proves equivalent loading of both generator and prime mover. That

is, for each kilowatt of load applied to the generator by the load bank,

an equal amount of electrical energy converts to heat by power

resistors, in a general way, this heat must be dissipated from the load

bank by air forced means or other convection.

The JMHing’s resistors are made by high quality finned tubular heating

elements, they are of the type where the surface area is enlarged by a

strip in order to heat gases. At high power the surface temperature is

small and the heating element is short. Meanwhile, Load elements are

cooled usually via Fan Forced Air, blower power is typically provided

by an outside source. Selected load banks are available with blower

power derived from the power source under test.

AC Resisive Load Banks

JMHing’s AC resistive load banks can be further divided into these categories:

A resistive load bank easily carried or pushed on

strong robust swivel wheels for testing and

maintaining AC power equipment such as UPS

systems and generators up to 150kW.

A resistive load bank for testing and maintaining

AC power equipment such as UPS systems and

generators at one location up to 4600kW. Many

models can be used as modular building blocks for

applications requiring capacity of tens or hundreds

of megawatts. Also the load banks can be loaded

on a trailer for more flexibility.

Resisive/Reacive Load Banks

The resistive/reactive combination load banks are used to test the engine

generator set or other electromagnetic devices working at their rated power

factor. We mainly manufacture three types of resistive/reactive load banks as

follow for different testing purpose.

RL load bank, combined with resistive load and inductive load to simulate

lagging power factor, is mainly for generator and UPS testing. In most cases this

is 0.8 power factor, and to achieve a 0.8 power factor, the reactive(inductive)

load should be sized at 75% of the resistive load bank kW rating.

We also manufacture RLC load banks, in this type of load banks, inductive or

capacitive load are reactive only and must be used in combination with a resistive load

to provide the desired load profile to test a power system. Reactive loads banks can

provide either a leading power factor (Capacitive) or lagging power factor (Inductive).

RCD load bank is similar to a reactive load bank in rating and

purpose, except that leading power factor loads are created. These

loads simulate certain electronic or non-linear loads typical of

telecommunications, computer or UPS industries.
