LTC25 Linear Temperature Controllers

Linear Temperature Controller, 1 mK stability 2.5A version.
For higher currents, see LTC 50, LTC 100 and LTC 2050

$375
- +

RedWave Labs Linear Temperature Controllers come in three versions: LTC25 with maximum current capabilities of 2.5A respectively, single supply operation (+5 to 30V) and temperature stability down to 0.001K. LTC25 has a variable current limiter up to the maximum current, various sensor capabilities (thermistors, RTDs, AD590, LM335), variable P-I setting, LED monitors and remote shutdown.
