RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while typing up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...

Wavelength Electronics Press Release - January 18, 2011
Wavelength Electronics Introduces RHM5K-CH
Precision Unipolar Temperature Controller
- Small, Simple, Low Cost PID Control with < 0.003ºC Stability
The RHM5K-CH can be used to achieve precision control at off-ambient temperatures. The PID control loop drives
resistive heaters or thermoelectric coolers. The RHM offers a high level of stability and can supply up to 5 A
with a small footprint. On-board 12-turn trimpots control temperature setpoint, proportional gain, and output
voltage limit. A single 10-pin terminal strip provides easy access to the DC supply, sensor, resistive heater, and
• Compact, 5 A Drive Current
• Single Supply Operation +5 V to +30 V
• < 0.003 °C
• Voltage Limit
• > +27 V compliance with +30 V input
• Supports Thermistors, IC
sensors or RTDs
• PID Control Loop
• Temperature Setpoint, Proportional Gain, and Limit Voltage are user
• Easy operation for resistive heater or thermoelectric
The RHM5K-CH is suited for
applications where heating or cooling (not both) is required. This product is ideal for applications where
temperature stability is critical and space is tight, such as heated optics (noncondensing circumstances), CCDs,
preheated liquids and chamber stabilization.
has simplified advanced laser diode drive and thermal control technology for OEM and research applications since
1993. Our high performance specifications are supported by a team of experienced sales and design engineers and a
top-notch manufacturing facility. Evaluation quantities are typically available from stock.
