DSPR320 is the latest model of Auber’s EZboil® series controllers. It is a digital power regulator designed for home brewers who want to automate step-mashing, low-oxygen brewing (LODO), and whirlpool after boiling. This model, DSPR320, is a step-up from EZboil® DSPR310D with a lot of newly added features including:
1) More flexibility in Mash and Boil programming. In DSPR320, the brewer can program boil steps in Mash Mode and can program mash steps in Boil Mode, which are not allowed in DSPR310D. The flexibility in programming enables the brewer to implement low oxygen brewing recipes and the whirlpool method automatically.
2) More relay functions are added. In DSPR320 different sections within a program, e.g. ramp-up sections, ramp-down sections, and timed steps are now clearly defined. A relay can be assigned to synchronize with a particular type of section in particular steps. For example, the brewer can assign the relay to drive a cooling pump to cool the wort at a desired step.
3) Easier to make changes on-the-fly. The user can change the set temperature, step timer, and jump steps while the controller is running the program.
4) Temperature deviation alarms are added.
In DSPR320, the programming in the Boil Mode is now essentially the same as in Mash Mode. So, for brewers who are already familiar with DSPR310D or the Brew Timer (JSL-73C), they need to adjust the boil program accordingly. Please see the manual for details.
Specifications:
Power input: 90 – 260 VAC, 50 Hz or 60 Hz.
Control resolution: 1%, or 1 °F/°C.
Control mode: burst firing mode* (see note below).
Temperature sensor input: Pt100 RTD.
Temperature display resolution:1 °F/°C.
Step timer range: 0 min to 99 hr 00 minutes with 1 min resolution.
SSR Output: 12 VDC, 80 mA (can drive up to 6 SSRs in parallel).
SSR requirement: Zero-cross, DC triggered AC SSR.
Alarm Output: 3 A for resistive load, 1 A for inductive load.
Dimensions:
Overall: 1.89 x 1.89 x 4.49" (48 x 48 x 114 mm), 1/16 DIN.
Mounting cut out: 1.77 x 1.77" (45 x 45 mm)
Length: 100 mm (from the front panel to the back); 114 mm if including the rotary knob.
Note:
1. The burst rate will between 1 and 100 pulses for each 100 AC cycles. The pulse width equals one AC cycle. It is automatically adjusted for 50 or 60 Hz.
2. The temperature sensor is not included. This controller can read PT100 RTD temperature sensors. Here is the link for RTD temperature sensors (Pt100 type) that can be used with this controller.
3. This unit should be used with SSR (see our 5A, 25A, 40A, 80A, 100A SSR), it's not compatible with solid-state voltage regulators (SSVR).
