Dear Sir,
On the above subject and reference, we are pleased to quote as follows. We
have quoted you for our Micro Controller Based Digital Series – which will go to give you
escalated taste of a Quality product – engineered by us to suit specific requirement of
users in CNC field requiring high speeds of correction and without the high speed gear box
and carbon brush incorporated D.C. Motors. The units use A.C. Step Synchronous Motors
only – which are low speed high torque permanent magnet rotor motors – which are burn

proof and they have no load current equal to full load current and further equal to locked
rotor current. High Quality Variable Transformer used add reliability unexpected hitherto
in the line and with the reliability achieved in the equipment, we are providing 5 YEARS
WARRANTY on the same.
A little bit about Ourselves:
We are one of the Oldest & Original manufacturers in the line – with all inhouse
manufacturing facilities – including those of the Variable transformers – which constitute a
sort of Engine for a Vehicle. We are established brand all over India and abroad for the
last 21 Years now. Ours is a QUALITY PRODUCT – that can live life upto 20-30 Years and
is designed to see that this needs least maintenance. We are exporting about 40 % of our
production to countries as Australia for last 10 years regularly.
We look forward to receive your valuable order and build up everlasting
relationship. Our Installation Base of these stabilizers is quite large and because of our
Quality and services, the Customer – once with us is always with us and thus in our
Customer List – there are repeated purchases running into 10-50 Stabilisers , by the same
user over the years 21 – since the time we are in this manufacturing.
We are quite confident that one trial with us – will give you utmost satisfaction
on the product and you will keep our product as brand preference.
In the mean time – we will like to assure you best of our attention & services
Thanking you

double Coupled Triacs for higher withstanding PIVs & long
life of triacs, workable in electrically noisy industrial
surroundings of welding sets, automatic Heater On-Off
environments with arrangement for Soft Start & soft
operation & no surges, free from jerks on Servo Motor,
gear or shaft, there by increasing life of Gears and Shaft
Bushes. The Cards before usage are Seasoned on
accelerated Switching Test Benches and are stressed with
Voltages to ensure long trouble free performance. The
Card ensures no hunting, no oscillations, and no noise
generation.
v Speed of

v Delay in
Switching On –
Soft start
Function
The Cards have built in provision to delay the switching on
by adjustable time from Power On Delay adjustment 1- 255
Seconds – after the supply goes off and again comes in –
so that the load always has a soft start and gets on only
after the operation of the stabilizer has stabilized.
The equipment is thus fully protected from incidences of
instantaneous power off & power on and generator
switching on after supply line failures.
v Frequency 47Hz. To 53 Hz.
v Generator
Compatible
Subject to quality of wave form output from the generator,
the unit is generator compatible.
