Charging Model: volvo high frequency machine is a microprocessor (CPU microarrays) as process control center, is complicated hardware analog circuit programming the microprocessor to the way the software program to control the operation of UPS Thus, the volume greatly reduced, greatly reduced weight, low manufacturing costs, the price is relatively low. High Frequency inverter frequency generally 20KHZ above, but high-frequency machine in harsh environmental conditions, the grid and poor tolerance DSE7310, compared applies to the grid more stable and less dust, temperature / humidity environment suitable charger Model: 3803639 Notes charger is forbidden to disassemble the charger should be placed upright DSE, carried out in dry and ventilated environment, avoid moisture, away inflammable and explosive materials under the conditions of the battery is full of DSE7320, disconnect the AC power input DSE7110, after disconnecting the connection between the charger and the battery or in the absence of long-term unused condition, you must disconnect the AC power charging process Do not cover the charger, the ambient temperature is not greater than 40 ℃ this charger is limited to indoor use, to guard against rain prohibited to charge non-rechargeable batteries twice boot time interval less than 10 seconds (off the input power) DSE5120, DSE, Dongguan City, South City Zhongxin Electrical and Mechanical operation provided by the Dongguan City, South City Zhongxin Electrical and Mechanical Services Department.
