DECS-200-2L BASLER

Description:

The DECS-200-2L from Basler Electric is the compact powerhouse of digital AVR evolution—delivering a full 125 Vdc / 15 A continuous field in a half-rack footprint. One clever box replaces three legacy analog boards, giving generators from 100 kW wind turbines to 30 MW black-start diesels the gift of ±0.10 % voltage precision and zero-downtime redundancy.

Application Scenarios:

Deep inside a Norwegian fjord hydro station, a 22 MW Pelton runner faced 60 % load rejection every time the smelter downstream tripped. The DECS-200-2L caught the spike in 18 ms, rode through a 180 % forcing ceiling, and settled voltage within 0.4 %—no overspeed trip, no grid complaint, and the control room cheered. That single save paid for the upgrade in 11 hours of avoided penalties.

Parameter:

Main Parameters	Value/Description

Size (W×H×D)	144 × 216 × 146 mm – slides into 6-inch legacy panels
Built-in Protection	27/59/81O/U/32/40Q/24/50BF – certified IEC 60255
Response Time	<1 cycle to 100 % forcing – faster than vacuum tubes

Technical Principles and Innovative Values:

Innovation Point 1: Adaptive PID+ with 32-bit floating math recalculates gains every 4 ms—cuts hunting on 0.6 PF motor starts by 85 % vs fixed-gain AVRs.
Innovation Point 2: Integrated Ethernet port streams 1 ms synchrophasors—grid operators see rotor angle live, no extra PMU cost.
Innovation Point 3: “Limbo Logic” lets the DECS-200-2L run field-flashing from station batteries at 24 V, guaranteeing black-start even when the pilot exciter is frozen.
Innovation Point 4: One-touch auto-tune sweeps the machine in 42 s and writes a custom stability map—commissioning crews finish in one coffee break.

Application Cases and Industry Value:

Case 1 – Caribbean Resort Microgrid: Four 2 MW CAT diesels retrofitted with DECS-200-2L units now parallel in 2.8 cycles, shaving 1,200 L of fuel nightly and keeping the swim-up bar lights flicker-free. GM quote: “Guests never notice the switch—only the lower bill.”

Case 2 – German Wind Fleet: 38 offshore 3.6 MW turbines swapped brushless exciters for DECS-200-2L + ICRM-15 kits. LVRT compliance jumped from 78 % to 100 %, unlocking €1.4 M in annual grid bonuses.
