Especially compact and easy-to-use, the new MINI-DC-UPS/24 DC/2 is a combination of the power supply unit and an uninterruptible power supply in the conventional ME housing. It secures the operation of all connected 24 V consumers in the electrical systems both in the case of an error-free supply network and in the event of mains interferences.
The combined solution enables a slim design with dimensions of 67.5 x 99 x 107 mm. The wide-range input allows input voltages between 85 V AC and 264 V AC; 2 A is provided at the output with a regulated and adjustable output voltage between 22.5 V DC and 29.5 V DC. The rechargeable battery module supplies an output voltage between 27.9 V DC and 19.2 V DC in the buffer mode. A 0.8 Ah or a 1.3 Ah rechargeable battery module is used depending on the required buffer time: The module thus supplies 2 A for five minutes with the 0.8 Ah rechargeable battery module or 2 A for 20 minutes with the 1.3 Ah rechargeable battery module. The buffer time varies depending on the load current.
The system availability is increased using extensive signaling through control lamps and active switching outputs. The charging process of the rechargeable battery module, the operational readiness, the buffer mode and the alarm messages are displayed before the rechargeable battery module is discharged. The service life of the rechargeable battery module can be increased by optimum battery management; for example, a temperature-compensated charging protects the rechargeable battery module at high ambient temperatures. An integrated timeout minimizes installation costs considerably.
