The Solaira Analog 150A, 120/240V Variable Heat Controller utilizes phase-angle firing to provide infinitly variable control of single-phase A.C. voltages to variable resistance loads for quartz/tungsten emitter and tube systems. These units are solid state and when operated within their stated ratings for current, voltage, and temperature, have no known MTBF or life expectancy rating. This Solaira Analog 150A, 120/240V Variable Heat Controller operates at 50° C (122° F) with no derating.


  • Solaira Analog 150A, 120/240V Variable Heat Controller
  • Power Circuit: inverse-parallel semiconductors selected for Vbo Clamping transient protection, with parallel R-C circuit for dv/dt protection. Current-clamping 2 millisecond power fuses in series with the power semiconductors provide short-circuit protection
  • Mains Frequency: 50/60 Hz standard
  • Output Voltage: 4% to nominal input voltage, infinitely variable
  • Overall Efficiency: 98.5 to 99.5%
  • Power Loss: approximately 1-2 watts/ampere/switched pole
  • Voltage Drop Across Power Circuit at 100% Output: 1-2 volts maximum per switched pole
  • Proof Voltage: (isolation between power circuit, control circuit and ground) greater than 2 kV
  • Control input: manual control via 75K Ohm potentiometer with Integral On/Off switch and calibrated dial plate standard
  • Unique “Vbo Clamping” provides unmatched protection for power semiconductors against transient voltage spikes common on commercial and industrial power mains
  • Two millisecond* fuses protect semiconductors against shod-circuit faults
  • Equipped with factory and approved fuses coordinated with power semiconductors
  • Proprietary heatsinks are engineered in-house, coordinating finite-element analysis (FEA) with on-site lab tests
  • Operates at 122 Degrees Fahrenheit with no derating
  • Rated voltage of the connected load should match the input voltage to the power control
  • Control Power: 5 watts minimum, derived from 12 VA isolation control transformer on all units
  • Transient Voltage Protection: voltage breakover (Vbo) protection with R-C filters for dv/dt protection
  • Note: Enclosure not included
  • How to Calculate which Solaira Analog Controller is Required:
  • Total Watts / Volts = Amperage
  • Always use maximum possible load current for sizing purposes
    • Example 1:
    • A. Total wattage: 3,000 W calculated as 2 heaters X 1,500 W
    • B. 120 Volts
    • C. Amp rating, calculated as follows:
      3,000 W / 120 Volts = 25 Amps - Since 25 is less than 30, Use Solaira Model: SOLA-SHP18230SOL - Amp rating: 30
    • Example 2:
    • A. Total wattage: 12,000 W calculated as 4 heaters X 3,000 W
    • B. 240 Volts
    • C. Amp rating, calculated as follows:
      12,000 W / 240 Volts = 50 Amps - Since 50 is less than 80, Use Solaira Model: SOLA-SHP18280SOL - Amp rating: 80
    • Example 3:
    • A: Total wattage: 30,000 W calculated as 5 heaters X 6,000 W
    • B: 240 Volts
    • C: Amp rating, calculated as follows:
      30,000 W / 240 Volts = 125 Amps - Since 125 is less than 150, Use Solaira Model: SOLA-SHP182150SOL - Amp rating: 150
    • Example 4:
    • A: Total wattage: 60,000 W calculated as 10 heaters X 6,000 W
    • B: 240 Volts
    • C: Amp rating, calculated as follows:
      60,000 W / 240 Volts = 250 Amps - Since 250 is less than 350, Use Solaira Model: SOLA-SHP182350SOL - Amp rating: 350
