Dual
Output Induction Heating Inverter
Multi-Coil
The unique
dual output induction heating
inverter (model M) consists of
two-phase locked inverters that will support multiple Induction
Heating Coils in order to produce very complex and demanding
Temperature profiles. Both inverters are continuously
phase-locked; each is independently controlled and corresponds to
a separate input or command signal.
New!
Uninterruptible Induction Heating Inverter
Mesta’s
new Uninterruptible Induction Heating Power Supply is equipped
with a “Built in UPS Function” that enables the
system to supply uninterrupted power to the customer’s furnace in the
event of a power failure. When
the AC line is present the system receives power from the utility to
support the load, while it charges the DC source (i.e. batteries) at a
precise rate. During a power/utility failure, the energy flow reverses
to support the load. This bidirectional energy flow is achieved thru an
intelligent power control, which results in a seamless operation.
The
“Built in UPS Function” eliminates the need for a large UPS
to power the customer’s furnace.
Incoming Utility power is connected directly to the Mesta power
supply, which is greater than 97% efficient. The additional power usage and heat generation of a large UPS is
eliminated. This approach
greatly increases the reliability and
efficiency of the
customer’s overall system.

Controllability/Optimal Precision
 |
Both the Model S (single inverter series) and Model M (multiple
inverter series) will control the output voltage better than one
part per 16,000 or 0.00625%. In a typical output of 500 Volts, the
system will be able to control the output voltages within +/-
0.03125 Volts. With a typical output power of 50 kW, the system
will be able to control the output power within +/-3.125 Watts.
This outstanding control allows the customer to precisely control
any parameter, yielding the most accurate results. |
|
| Control
of the Output Voltage
| An external 4-20 mA source controls the magnitude of output
voltage between 0 and the rated output voltage of the unit. The
output frequency (9-11kHz) is programmable to equal the maximum
resonance of the given system. |
|
| Highest
Efficiency (>97%)
|
The Mesta approach produces low associated losses and yields high
efficiency. The energy efficient Mesta inverter will dramatically
reduce operating costs and preserve profitability to help your
company and product maintain a competitive edge. |
|
| Air
Cooling-No H2O
|
Due to the high operating efficiency, the Mesta Induction Heating
Inverter uses air-cooling instead of water-cooling eliminating any
associated water or maintenance costs. Mesta has perfected the
induction heating process incorporating the most state of the art
magnetics and powerful micro controller intelligence into a
water-free, cost-efficient system. The Mesta IHI will pay itself
off in the savings of associated water costs and maintenance
alone. |
|
| Serial
or Remote Communication
|
Mesta's induction heating inverter is user friendly and allows the
user to continuously communicate with the system and monitor
and/or program specific operating parameters. This can be done
through the advanced front panel (16 button keypad) and (40x8)
character LCD Display, or serially through the computer keyboard
via the RS-232 connection. |
|
| Tap
Changing Option
|
Changing the Output Tap Voltage is optional on the Mesta Induction
Heating Inverter. The Tap Changing Inverter produces rated power
at different maximum voltages ranging from 300-1000 Vrms. This is
ideal for applications where the voltage/current characteristics
of a driven furnace are not entirely known or for applications
where the driven furnace is changed from time to time. |
|
| Diagnostic
and Critical Annunciations
|
The micro-controller of the induction heating inverter will
automatically self-diagnose unusual or dangerous operating
parameters and instantaneously alert the operator with its
advanced alarm system. Further, it captures the time and reason of
the occurrence to facilitate troubleshooting and ensure minimal
downtime. |
