If a DC supply is required one may order from MHI or elsewhere. DC power supplies unlike the AC supply panel will not offer a feedback control.
Please note the following if a non-MHI supply is employed: Most DC power supplies max-out somewhere in their rated current or voltage (and power) but often allow independent control of each parameter – please check with supplier All these features will normally be called out be in the power-supply manual provided by the supply manufacturer.
The current should not exceed 17-20 amps for a SIG24-400-1400
The SIG24-400-1400 heater will glow close to its highest temperature for 17-20A current with a corresponding potential of ~18-24V in a free radiating mode. without insulation cover. Use for igniter or radiator.
An AC current controller enabled with a temperature feedback and power control mechanism may also be used instead of a DC power supply. The BPAN-O-PLUS is recommended as a possible AC controller. The main features of this AC control panel are listed on https://mhi-inc.com/PG4/electronic-controllers-control-panels.html. Please contact MHI at 513-772-0404 for more details.
Element GAXP-IgMp. The more accurate measurement technique at these temperatures is a radiation pyrometer.
Electricals: Maximum is 400 Watts.
The maximum temperature is achieved for ~ 17A with full power and maximum temperature when the IG24-400 is used in moderately free radiative conditions (upto 20A RMS meter read-out in fully free-radiating conditions)
A 24V minimum supply rated for 17 Amps (variable) is the minimum required for heating to glowing conditions.
A power supply is offered in the category of the optional item available for this microheater. This is the 24V DC (nominal) power generator/supply.
When requiring to power more than two such microheaters simultaneously, a BPAN-O or BPAN-O-PLUS with feedback control is recommended. Please contact MHI for details (513-772-0404).
Heating Rate: Instantaneous. The heater will start getting hot as soon as power is introduced to it. Typically one will notice a glow (i.e when it is above ~800°C) in the order of less than a minute when it is powered up in a normal manner.
The hot zones on each leg are 0.5″ long.
The rated amps and voltage are called out for use in a free radiating mode.

Yes – the terminals will get hot but will take the heat.

“We have used the heater, it is working well. Do you have calibration chart (Temperature v/s Voltage) for this MC170 microheater. ……………..Since we do not have temperature measuring tool for such a high temperature (1900C)…………..We are planing to order one more heater………………….”

Several years ago we have bought in your company the front loading M18-40 furnace and two robust radiators and got much satisfaction working with them. Now, we believe, it is a very time to substitute heating elements in the furnace and to buy new radiators.
