DC power supplies
A DC power supply, also known as a DC voltage supply, is actually a collective name for many different types of power supplies. At TTMS, we start by distinguishing between fixed DC power supplies (one specific output voltage) and adjustable DC power supplies, where the output voltage is adjustable between usually zero and the maximum value of the specific power supply.
TTMS only has stabilised power supplies in its range. These are DC power supplies that deliver a stable voltage or current independently of the load.
Next, we can then differentiate based on:
Linear or switched mode power supplies
Multi-channel power supplies
Constant power supplies, where the maximum voltage and current are determined by the maximum power of the power supply
Low or high power (>1500W)
Low or high output voltage (>600V)
Arbitrary DC power supply
Two quadrant power supply (+V, ±A or +A, ±V)
Four quadrant power supply (±V and ±A)
Regenerative DC power supply (When the current is negative, energy is supplied back to the grid).
Almost all power supplies have a standard or optional option of an analogue or digital interface (RS232, RS485, GPIB, USB or LAN / LXI).
Using the filters, you can already make a selection for the right type of DC power supply. However, there are then often still many possibilities. Our total range of DC power supplies consists of many hundreds of units, each with their own options.
