MD33D5FB00 - Carel MasterCella Temperature Controller 30A 16A 8A 8A 2HP 230V BUZ 2NTC 3DI IR RTC M.SW

MD33D5FB00 - MasterCella Temperature Controller 30A 16A 8A 8A 2HP 230V BUZ 2NTC 3DI IR RTC M.SW MasterCella represents one of the leading products in the CAREL refrigeration range. MasterCella manages smart defrosts, consequently ensuring energy savings in the system as a whole, and can be fitted with a clock for real time defrosts (rather than at set intervals, as is usually the case). In the models fitted with clock, HACCP management is standard: this guarantees control over the temperature of stored foodstuffs, in compliance with the requirements of the HACCP system.

MasterCella represents one of the leading products in the CAREL refrigeration range.

 

Easy to use

MasterCella comes with a very powerful display that shows 3 digits plus decimal point, minus sign and icons that make the values and operating status simple to read; the keypad is ergonomic and easy to use.

HACCP: special surveillance

MasterCella automatically manages the monitoring of the unit, highlighting any critical situations. The MasterCella series simplifi es the HACCP procedures by notifying the user of the correct temperature trend, activating a local alarm (buzzer) and remote alarm (via the special relay) when the maximum set limit is exceeded.

Made-to-measure for each customer

The appearance can be customised by simply replacing the top and bottom covers, adding specifi c colours or company logos.

Greater safety

Models are available with the 32 A door interlock disconnect switch option for complete unit on/off management. This solution makes the MasterCella a complete electrical panel. The disconnect switch can be locked in the “OFF” position to ensure maximum safety when carrying out maintenance on the cold room.

Cable inlet from below or above

The electrical cables can run to the instrument through standard plastic conduits that are fastened directly to the case.

Time-based defrost

The clock is used to record data in a detailed and precise way, and set the defrost function based on the real time (and not in intervals, as is usually the case). The RTC clock also ensures conformity with the HACCP standards, and its operation is guaranteed for at least 10 years.

Control of large compressors and lights

Most of the models come with a 16 A / 2 HP relay, which can directly control heavy loads such as refrigeration compressors or actuators for managing the lights, including fl uorescent lights, without the need for further intermediate relays.

Removable bottom plate

The bottom plate that houses the power board and the control devices and/or accessories can be easily removed. This allows the panel to be wired before installation, and the holes to be made in the case for inserting the cables.

Easy to connect

Electrical wiring is made easy by the openable cover at the front and the considerable space inside to house the main switch or other auxiliary devices.

Everything under control

The standard MasterCella supply includes 3 digital inputs, which can also be confi gured as NTC probe inputs, and ensure the following functions: monitor a third point of temperature measurement (this can be displayed on the repeater display); manage the “end defrost” completely and independently, by confi guring additional parameters; manage the condenser fans using the auxiliary output; signal the high temperature alarms and the need for maintenance on the unit.
