Frequently asked questions
Common questions about our products, services and support.
What does Impress Corporation Limited supply?
Uninterruptible power supply systems, automatic voltage regulators and stabilizers, circuit breakers, switches and sockets, contactors, protection relays and surge protection devices, lightning protection and earthing materials, grounding materials, raised access flooring, and batteries and accessories.
Do you only supply equipment, or do you install it as well?
Both. We design and specify the system against your load, supply the equipment, and carry out installation and commissioning. We also provide preventive maintenance and after-sales service.
How do I get a quotation?
Send us the equipment type, required rating and quantity — and a load list or bill of quantities if you have one. Contact details are on the contact page.
How quickly can you respond to a service request?
After-sales service requests are responded to around the clock. For non-urgent technical and commercial enquiries, our office hours are saturday – thursday, 09:00 – 18:00.
How is battery backup time calculated?
Backup time depends on the connected load in watts, the battery capacity in ampere-hours, the battery voltage and the inverter efficiency. Because capacity falls as load and temperature rise, an accurate figure comes from the battery manufacturer’s discharge tables rather than from a simple division. Send us the UPS model and the load and we will calculate it.
Where are you located?
House 183/5, Road 2, Block A, Mirpur-13, Dhaka-1216, Bangladesh. Office hours are saturday – thursday, 09:00 – 18:00; the office is closed on Friday and government holidays.
