| 1983 |
First
production run shipped out in early January. |
| 1985 |
To
better serve its customer base, software programs
were developed to calculate transformer data
based on customers' DC data after rectification.
With these programs, the first prototype is
guaranteed to meet the customer's specifications. |
| 1986 |
Toroid's
standard design transformer line received UL
recognition to the more demanding UL1411 that
replaces the old and more lenient UL506. |
| 1987 |
Toroidal
DC filter chokes for 60Hz were introduced to
offer a better solution to using large filter
capacitors for applications with high voltage
requirements. |
| 1988 |
A
satellite plant was opened in Salisbury, MD
adding 6,000 sq.ft. to the existing 10,000 sq.ft.
in Bowie, MD. All long runs were made at the
new plant. |
| 1989 |
A
new standard transformer series for 12V halogen
lamps was introduced. |
| 1990 |
In
December, the manufacturing operation in Bowie,
MD was transferred to Salisbury, MD. |
| 1991 |
In
April, the Bowie plant was closed and the sales
and administration were relocated to the Salisbury
plant. |
| 1992 |
Several
new standard design product lines were introduced,
including Isolation transformers for commercial
and medical equipment, expansion of the line
of Rectifier Transformers for 115/230V, 50-60Hz
operation. A family CSA certification was obtained |
| 1993 |
The
ground breaking ceremony of a new 20,000 sq.ft.
plant was held in July. The actual move took
place in December. The line of medical grade
standard isolation transformers was expanded
to include 100VA to 5000VA. Additional mounting
hardware options were introduced. |
| 1994 |
Custom
designed High
Frequency Magnetics were
added. The design and manufacturing capabilities
were purposely limited to toroidal and potcore
designs. |
| 1995 |
A
new line of standard design 115/230V step-up
or down Auto-transformers was introduced. |
| 1996 |
In
April, a new line of standard design aluminum
encased hospital
grade isolation transformers
was introduced. |
| 1998 |
New
international
isolation transformers with CE marking
and IEC320 outlets were introduced. |
