Micro soft dc ac

Powerful designed, Micro AC-DC UPS 1. Wide AC input range from 90 to 300VAC. It can avoid the AC peak voltage when AC is recoverd. 2. DC output design, transfer time from AC failed to battery mode is only 4ms. High efficiency support from battery power to DC output. 3. Max. 50W output, the range can be designed from 5~50VDC setup by manufacture before delivery. Most of output voltages are 48V, 24V, 12V, 9V, 7.5V and 5V. 4. The end user can decide the battery capacity depends on backup time they need. Micro AC-DC UPS can work with most of popular 12VDC Lead Acid Maintenance free battery cell. The capacity from 1.2Ah to 20Ah are supported. Our Individual charger can support 1000mA charging current. So, we suggest list the largest battery cell is 20Ah. The Lead Acid battery cell is the most popular battery in the world, therefore, end user can easily to find replace battery in the local market and no after service cost, too. We also suggest importer can import Micro AC-DC UPS without battery, to save freight cost and import tax of battery. 5. Reversed polarity protection, to avoid the end user connected wrong polarity to damaged Micro AC-DC UPS. Our design the battery cell is external connection, the benefits are : 1. Save the freight cost for importer, because only need to import the Micro AC-DC UPS Main Body. 2. Importer can use the most of popular lead acid maintenance free battery from local vendor. No need to pay battery import tax. 3. And, to work with the wide range battery cell from 12V/1.2Ah to 12V/20Ah supported for different backup time. 4. The end user can easily to do after service for battery. If you have any idea, please feel free to let me know!

Description: Details iShopping.pk brings you the best price for Bosch CCS-CU Control Unit For CCS 900 Ultro Conference System with express shipping all over Pakistan.   The Bosch CCS-CU Control Unit is the central power and control station for all CCS 900 Ultro Conference System contributor units, such as the chairman and delegate units. The control unit will supply power for up to 50 delegate / chairman units, and provide control for up to 150. The unit features a built in speaker and automated, programmable control over contributor units without the need for an operator. Its Digital Acoustic Feedback Suppression (DAFS) eliminates feedback howling and maintains clear, intelligible speech. Plenty of connections allow for interfacing within paging systems, amplifier systems, recording devices and more. The unit is feature rich, however its control section is straightforward and intuitive to operate in any conference setting.   Features: Discussion Control Without Operator The CU can be setup to operate standalone without the need for an operator. The following 5 modes can be chosen using a rotary control on the unit's top panel: • Open mode - allows selection of one to four microphones (excluded chairmen microphones) which can be simultaneously active • Open mode with auto-switch-off - allows selection of one to four microphones (excluded chairmen microphones) which can be simultaneously active. If the delegate does not speak for 30 seconds, microphones are automatically switched off • Override mode - delegates can override each other simply by activating their microphones. Only one microphone can be active at any one time. (Note: In override mode, delegates cannot override chairmen) • Chairman only mode - only chairmen can speak. Delegate microphones cannot be activated, even when a chairman is not speaking • Test mode - checks if system connections are correct. All microphone light rings and contribution unit LEDs light up to indicate that units are properly connected Supplies Power for up to 50 Contribution Units The CU has two trunk outputs for the loop-through connection of contribution units. It is possible to connect 25 contribution units to each trunk output, with a maximum system cable length of 109.3 yards (100m). Provides Control for up to 150 Contribution Units Up to 3 CUs can be used together in a discussion system to power and control a maximum of 150 contribution units. In this configuration a single CU acts as a master controller for the entire system. Built-in Monitor Loudspeaker The built-in monitor loudspeaker and headphone socket allow the conference to be monitored. Interfaces the System With External Equipment The following equipment can be interfaced to the CCS Ultro Discussion System through the CU: • External wired or wireless microphone - for guest speakers or audience participation. (Note: The external microphone is muted when the priority button on a chairman unit is pressed, and when the system is operating in 'chairman only' mode) • External PA system - for transmitting the proceedings to an audience in the same room or an adjacent room• Tape recorder - for external recording and playing back meetings and discussions • Audio equipment - for providing background music • Telephone coupler - to allow a remote delegate to participate via telephone• External audio processing - an insertion connector is provided Controls and Indicators (Top) • Mains on/off switch • Graphical display for status information (CCS‐CURD) • 5 soft buttons for configuration and control of thebuilt-in MP3 recorder (CCS‐CURD) • Loudspeaker volume control, for setting output level of loudspeakers of contribution units. This control also determines the maximum level for the headphone outputs of the contribution units and the CU. • Microphone mode rotary switch, for setting the number of simultaneously active microphones, and selecting one of the four operation modes (plus test mode) • Power on LED Controls and Indicators (Back) • On/off switch for digital acoustic feedback suppression facility (CCS‐CUD, CCS‐CURD)• Microphone input gain adjustment • External recorder input gain adjustment• Insertion connector bypass switch   Specifications: Connections Top • 1x 0.14" (3.5mm) stereo headphone socket Back • 1x AC input • 2x 7-pole circular female connectors, trunk in/out loop through interconnection  • 1x 3-pole female XLR connector, microphone input (can be used as line input by included 50dB attenuator) • 1 x Cinch connector pair, line input/output  • 1 x Cinch connector pair, telephone input/output • 1 x Cinch connector pair, insertion input/output  • 2 x Cinch connector pairs (R/L channel), external recorder input/output • USB interface (CCS-CURD) Power Supply Mains voltage: 100 to 240 VAC ± 10% Current consumption: maximum 0.9A (100 VAC) to 0.3 A (240 VAC) DC supply to contribution units: 24V ± 1V (current limited) Volume mute (50dB att.) + 10 steps of 1.9dB Limiter 10dB above nominal level loudspeaker / headphone Gain Gain reduction due to number of open microphones (NOM): ÷ NOM ± 1 dB Total Harmonic Distortion Nominal input (85 dB SPL): Max. input (110 dB SPL): Sample Rate Recording: 32kHz Playback: 32, 44.1, 48kHz Bit Rate Recording: 64, 96, 128, 192, 256 KBit/sec Playback: any bitrate Mount Tabletop (portable or fixed) 19-inch rack flush mounting Material Top: polymer Bottom: painted metal Color Charcoal and Black Dimensions (HxWxD) 3.4 x 14.2 x 5.6" (84 x 361 x 143mm) Height of feet: 0.22" (5.5mm) Weight 3.3 lb (1.5kg)
