Product Overview
Description
Performance characteristics
n High precision frequency stabilized voltage regulator,regulate the voltage and frequency by knob type fast.
n The speed of transient response is fast.
n High precision,4 windows measure and display at the same time:frequency,voltage, current,power,power factor,don’t need to switch.
n It has multiple protection of over voltage,over current,over load,over temperature and alarm function.
n No radiation interference,including harmonic components,and no interference after the special treatment.
n Provide the world standard voltage,frequency,analog test a variety of electrical products

Means:
*About voltage and current(eg. RK5001)
RK5001 is 1000W have two range, 0-150V /0-300V(all model have two range 0-150V/0-300V)
voltage= power / current
When in 120V 8.4A is max
When in 240V 4.2A is max
then,in range 0-150V,if you let it output 110V or other lower votage, max current can not over 8.4A, it means 8.4A is max.
the same as 0-300V range, if you in this range, max current can not over 4.2A
We can special order 0-500V, Power is constant, voltage goes up, current goes down,
That means if still RK5001(1000W), 0-250V/0-500V(special order)
when in 500V ,2A is max
When in 250V ,4.2A is max
if you want the voltage in 500V, and current more than 2A, you need choice more power,
*About Frequency:
45-70Hz,50Hz,60Hz,2F,4F,400Hz
means 45-70HZ can be adjustment(55Hz,60Hz...)
50Hz,60Hz,2F(100Hz),4F(200Hz),400Hz is fixed(can not be adjustment)
We can do special order 45-400Hz can be adjustment.
sorry specail order have not manual,the manual is for standard model.
Specail order is different price with the standard order, and usually standard
order is in stock but specail order need waiting 5-7 days.
