Digital SSR Power Regulator for Wort Boiling Control

This digital solid state power regulator (DSPR1) is for manually adjusting the power output on a solid state relay (SSR). It can be used for controlling wort boiling during beer brewing. User can adjust the SSR output power from 0% to 100% by turning the digital rotary encoder with 1% resolution. Changing the numeric value is much easier using the rotary encoder than using the key pad as in our PID controllers. In contrast to our SSVR, this unit is able to regulate the power almost linearly, with high precision, good reproducibility, and low electromagnetic interference (EMI).

Specifications:
Power input: 90-260VAC, 50 Hz or 60 Hz.
Control resolution: 1%.
Control mode: burst firing mode* (default), time proportional mode**. (See Note1 below)
Output: 12VDC, 80 mA. (can drive up to 6 SSRs in parallel)
SSR requirement: Zero-cross, DC triggered AC SSR.

Dimension:
Front: 48x48 mm (1/16 DIN).
Mounting cut out: 45 x 45 mm.
Length: 86 mm (from the front panel to the back); 100 mm if include the rotary nub.

Note1:
* The burst rate will between 1 and 100 pulses for each 100 AC cycles. The pulse width equals to one AC cycle. It is automatically adjusted for 50 or 60 Hz.
** Cycle time: 1-99 seconds.
